Ionic 2 Range With Labels - html

I am looking to add some labels to an Ionic 2 range element (the documentation for which can be found at http://ionicframework.com/docs/v2/api/components/range/Range/)
You can add a label at the beginning and end using the following markup
<ion-range min="-200" max="200" [(ngModel)]="saturation" color="secondary">
<!-- Setting the labels here -->
<ion-label range-left>-200</ion-label>
<ion-label range-right>200</ion-label>
</ion-range>
I would however like to add some labels throughout the range, on either side if possible in an attempt to make it look more like a progress bar. So you might have labels like 25%, 50% etc ..
What would be a good way to approach this, without interfering too much with the Ionic HTML?
My approach so far is just to create an ion-row above the range, then use css to place it.
HTML
<!-- TIMELINE -->
<div class='timeline'>
<ion-grid class="timeline-grid">
<ion-row class="timeline-labels">
<ion-col width-20>Label One</ion-col>
<ion-col width-20>Label Two</ion-col>
<ion-col width-20>Label Three</ion-col>
<ion-col width-20>Label Four</ion-col>
<ion-col width-20>Label Five</ion-col>
</ion-row>
<ion-row>
<ion-col>
<ion-item>
<ion-range color='secondary' [(ngModel)]="progress">
</ion-range>
</ion-item>
</ion-col>
</ion-row>
</ion-grid>
</div>
CSS
ion-row.timeline-labels {
padding-left: 20px;
z-index: 1;
position: absolute;
top: 10px;
}
Which does in a way work, however I am thinking there is maybe a better/cleaner way to go about it.
Any advice would be great.
Thanks!

Wouldn't setting the pin="true" (in the range slider tag) basically do what you want?
It would show the current value of the slider like a progress bar would.
If you are looking to achieve more of a specified label at the bottom at specific points I think the best way would be to add a div with spans directly below the range slider and then toy with the CSS till its close enough to what you want.
main css issues will be removing padding or margin space around the Range element, and then getting the font size and spacing of the 'progress' in the right spots.
eg.
<ion-range min="0" max="100" pin="true">
<!-- Setting the labels here -->
<ion-label range-left>0</ion-label>
<ion-label range-right>100</ion-label>
</ion-range>
<div>
<span>20%<span>
<span>40%<span>
<span>80%<span>
<span>100%<span>
</div>

This might be too late but for others looking in the future I put my labels inside of spans within a label below and used css to style the padding and width.
Here is my HTML:
<div class="slide-rating">
<ion-range min="1" max="4" step="1" snaps="true" ticks="false" ></ion-
range>
<ion-label class="rating-labels">
<span> Beginner </span>
<span> Casual </span>
<span> Advanced </span>
<span> Expert </span>
</ion-label>
</div>
And my CSS:
span{
color: #354D37;
font-family: Gotham-Book;
font-size: small;
padding-left: 12px;
}
.slide-rating{
align-items: center;
width: 80%;
position: absolute;
top: 70%;
left: 50%;
transform: translate(-50%, -50%);
}
.rating-labels{
margin-left: -5%;
margin-right: -5%;
text-align: center;
}

Creating a side bar using HTML + CSS in Ionic Framework

I am trying to create a page with the Ionic Framework and Angular which has a sidebar, and some text content against that sidebar. Right now, the sidebar works well, but when I try to add some text content, the text ends up underneath the sidebar. I am assuming this is because the sidebar is positioned as absolute, and thus is out of the document flow.
Here is my current code:
<div id="sidebar_button_container">
<ion-button href="start-game" color="dark" expand="block">{{ newgame_text }}</ion-button>
<ion-button href="view-previous-games" color="dark" expand="block">{{ viewgames_text }}</ion-button>
</div>
<div id="text_content">
Test. Example Text, This is so that I can read it wherever it is.
</div>
#sidebar_button_container {
text-align: center;
position: absolute;
left: 0;
top: 55px;
bottom: 0;
padding-right: 5px;
padding-left: 5px;
background-color: #dddddd;
}
#media screen and (min-width:400px) {
#sidebar_button_container {
right: 80%;
}
}
#media screen and (max-width:400px) and (orientation:portrait) {
#sidebar_button_container {
right: 50%;
}
}
#media screen and (max-width:600px) and (orientation:landscape) {
#sidebar_button_container {
right: 60%;
}
}
(Btw, the top position of the sidebar is because there is an ion-toolbar at the top of the page, and the media checks are only tested on my phone and laptop, and are included here only for a more complete picture of my code.)
In this picture, you can see that the text in the text_content div is hidden behind the sidebar. I would like to know how I could position the text against the sidebar instead of behind it, while keeping the sidebar intact, and preferably without hardcoding a lot of values in when I want to add paragraphs or line breaks.
You can try a number of things.
The first one that comes to mind for me at-least is to add a CSS padding-left property to "text_content". Short term I don't think this is the best solution, given you will likely have various screen dimensions, and on smaller screens the padding might push the text too much to the right.
The Second idea that comes to mind would be to create a parent/container div. (as shown below) and try adding some flex-box to the "container" CSS class using the following resource (https://css-tricks.com/snippets/css/a-guide-to-flexbox/).
<div id='container'>
<div id="sidebar_button_container">
<ion-button href="start-game" color="dark" expand="block">{{ newgame_text
}}</ion-button>
<ion-button href="view-previous-games" color="dark" expand="block">{{
viewgames_text }}</ion-button>
</div>
<div id="text_content">
Test. Example Text, This is so that I can read it wherever it is.
</div>
</div>
The last potential idea/solution I have would be to make the "text_content' relative to the parent. You can find an example of how to do that here (Position absolute but relative to parent).
I hope this helps you find the solution, this is one of my first Stack Overflow contributions, so apologies for not being able to provide an immediate answer. (If you have a public repository you are willing to share, I could clone down your project, and do some more tinkering myself). Cheers.
You should have a look at ionic grid
You can write something like
<ion-grid>
<ion-row>
<ion-col size="2">
<ion-button
href="start-game"
color="dark"
expand="block"
>{{ newgame_text }}</ion-button>
<ion-button
href="view-previous-games"
color="dark"
expand="block"
>{{ viewgames_text }}</ion-button>
</ion-col>
<ion-col>
Test. Example Text, This is so that I can read it wherever it is.
</ion-col>
</ion-row>
</ion-grid>

ion-grid with alternate columns

I'm not very familiar with Angular. I would like to have a grid like this:
i.e. have one image per row alternating with two images.I tried with this code but I get a slightly different grid (I also get the same image twice because I don't know how to increase the index inside the loop):
.html:
<ion-content>
<ion-grid class="design">
<ion-row size="12" *ngFor="let t of types ; let i=index">
<ion-col *ngIf="i%3==0" size="12">
<img oncontextmenu="return false;" src={{t?.img}} class="center" />
</ion-col>
<ion-col *ngIf="i%3!=0" size="6">
<img oncontextmenu="return false;" src={{t?.img}} class="center" />
</ion-col>
<ion-col *ngIf="i%3!=0" size="6">
<img oncontextmenu="return false;" src={{types[i+1]?.img}} class="center"/>
</ion-col>
</ion-row>
</ion-grid>
</ion-content>
.scss:
.design {
position: center;
width: 90%;
height: 90%;
margin-left: auto;
margin-right: auto;
}
.center {
display: block;
width: 100%;
}
How could I modify it ?
You need to wrap rows in ion-row element and everything in the ion-grid, then you can use ion-col for each column. Here is the simple example of full-width element and 2-column row: https://stackblitz.com/edit/ionic-yxpfht?file=pages%2Fhome%2Fhome.ts
You may also refer to the official docs since there is a nice example as well of how to use grid. Additionally, you may want to manipulate spacing/gutter, which is explained in the docs.
And if you have your images in array, like this `['img1', 'img2', 'img3'] you may want to check if you have 3 to display them 2 + 1 (2 in the first row and 1 in the second), so then you can just use something like on the stackblitz example.

ion-Checkbox only on box clickable

I want to separate my <ion-checkbox> from <ion-label>. So the main issue is that I have to display additional informations if you click on the label, but you should not activate the checkbox. The checkbox should only be activated, if clicked on the "checkbox icon/checkbox square".
<div>
<ion-list>
<ion-item *ngFor="let list of list">
<ion-label (click)="showAdditionalInformations()">{{list.item.free_text}}</ion-label>
<ion-checkbox *ngIf="list.item.checkbox==true"></ion-checkbox>
</ion-item></ion-list>
</div>
Can someone help me?
This does not work with Ionic 4 because Shadow Dom creates a button element that overlays the label element and captures the click events.
A workaround for Ionic 4 is to wrap the ion-checkbox with a span, and make it relative.
This way, the button in the Shadow Dom will fit only this new span, keeping the label free to asign a custom click event.
<span class="checkbox-container">
<ion-checkbox slot="end" formControlName="accept"></ion-checkbox>
</span>
.checkbox-container {
position: relative;
}
For ionic-4, give the property "position:relative" to ion-checkbox. It works !
ion-checkbox {
position:relative;
}
You can try to add this piece of code to your CSS. It will hide the overlay which wraps both your checkbox and your label.
ion-checkbox .item-cover{
display:none;
}
This did the trick for me:
ion-checkbox {
.item-cover {
width: 70px;
}
}
For ionic 4 there is a workaround by using the start slot of ion-item as laid out here.
<ion-item lines="full">
<ion-icon slot="start" name="at" (click)="iconClicked()"></ion-icon>
<ion-label slot="start" (click)="labelClicked()">
This is a separately clickable label
</ion-label>
<ion-checkbox slot="end"></ion-checkbox>
</ion-item>
With lines="full" the bottom border is fixed.
For whoever gets here via Google like me, using Ionic 6 (2022) - I resolved this issue giving the label a z-index:3.
This also works for an ion-button slotted at end.
<ion-item>
<ion-label>Select/unselect all</ion-label>
<ion-checkbox slot="start" (ionChange)="selectAllFarmers($event)"></ion-checkbox>
<ion-button style="z-index:3" slot="end" (click)="exportSelectedFarmers(remoteFarmers)">Export selected</ion-button>
<ion-button style="z-index:3" slot="end" (click)="finaliseSelected()">Finalise farmers</ion-button>
</ion-item>

ion refresher and fixed element

index behind other div
I drawed a red ligne where the index were
so i have a div which is fixed, but with my ion-refresher,
the fixed div seem to go in absolute when i pull to refresh, i don't know how to fix this.
here my code
.alphabetItem {
color: #ffffff;
font-size: 10px;
position: fixed;
z-index: 99999999;
right: -4%;
top : 200px;
}
<ion-refresher (ionRefresh)="doRefresh($event)">
<ion-refresher-content pullingIcon="arrow-dropdown" pullingText="Tirer pour rafraîchir" refreshingSpinner="circles" refreshingText="Relâcher pour rafraîchir ...">
</ion-refresher-content>
</ion-refresher>
<ion-col col-1 class="alphabetItem" scrollY="true" style="width:100%; height:100%">
<div class="divLetter" *ngFor="let letter of alphabets" (click)="alphaScrollGoToList(letter)">
{{letter}}
</div>
</ion-col>
Try to use ion-toolbar component from Ionic Framework (https://ionicframework.com/docs/api/components/toolbar/Toolbar/).
<ion-header>
<ion-toolbar>
<!-- your fixed col -->
</ion-toolbar>
</ion-header>
<ion-content>
...
<!-- your content + refresher -->
...
</ion-content>
The ion-refresher is a really special component. No matter where you place it, it will be put at the top of the nearest ion-content. When you refresh, it will move down your scroll-content, where your fixed container is placed in. <ion-toolbar> should fix this problem.

CSS Width not being set as expected

I have the following. As you can see, I have a row with two columns. I set the first column to a width of 90%, and the second column to a width of 10%. But as you can see, the columns are the same length.
I have the following css:
.message-footer-col {
width: 90%;
}
.message-footer-button-col {
width: 10%;
}
If anyone can advise how I can adjust each columns width, I would appreciate it. Thanks
UPDATE
I am using an Ionic2 framework that generates the raw html. Here is my code:
<ion-footer class="message-footer">
<form #f="ngForm">
<ion-grid class="message-footer-grid">
<ion-row class="message-footer-row">
<ion-col class="message-footer-col">
<ion-input class="message-footer-input" [(ngModel)]="message" name="messageText" required placeholder="message..."></ion-input>
</ion-col>
<ion-col class="message-footer-button-col">
<button class="message-footer-button" (click)="messageSend(f.value, f.valid)" full [disabled]="f.valid === false"><ion-icon class="message-send" name="send"></ion-icon></button>
</ion-col>
</ion-row>
</ion-grid>
</form>
</ion-footer>
First remove col class as it has some flex properties,
then apply display:block; to the columns.
