I have a asp:DropDownList with fixed width of 150px, but its list items are not enough to fit in 150px width, so it get cut off in IE (works fine in other browsers)
I search about this, but only got solution for html SELECT.
set a css class for your dropdownlist and then set width to that css class
<style>
.myDropDown
{
width : 150px;
}
</style>
<asp:DropDownList CssClass="myDropDown"></asp:DropDownList>
EDIT
so you must remove width attribute from your dropdownload. then it will be resized depending on items size.
<script type='text/javascript'>
function SetWidthToAuto(drpLst) {
drpLst.style.width = 'auto';
}
function ResetWidth(drpLst) {
drpLst.style.width = '150px';
}
</script>
<div style="width:150px;overflow:hidden;">
<select id="drpTechnology" style='width:150px' onchange='ResetWidth(this)' onblur='ResetWidth(this)' onmousedown='SetWidthToAuto(this)'>
<option value="-1">Browse me..</option>
<option value="1">Short Option</option>
<option value="2">Little bigger than short Option</option>
<option value="3">Largest option available with this select box</option> </select> <div>

I use select element with fixed width. However, when I have option element nested in select, which has quite long text, then, when this option is being selected, it does not get full background-width (I want the background to be 100%) and also the text is hidden.
Here is the example with the last option being hidden.
.x {
width: 200px;
overflow-x: auto;
}
<select class="x" size="4">
<option class="y" selected>xyz</option>
<option class="y" selected>xyz</option>
<option class="y" selected>xyz</option>
<option class="y" selected>xyzxyzxyzxyzxyzxyzxyzxyzxyzxyzxyz</option>
</select>
You can see the full width using a single css property . Please add a class to solve the issue :
.y{
width: fit-content;
}
Using this style, you could see that the background color gets filled to the full width.
I have a div with some content that gets hide after 5 seconds but below it, I have a drop-down with some options. So what happens when the select box is open and at the same time the div gets hidden, the options box remains in the same place and doesn't shift upwards with the select box.
Creating a custom drop-down is not an option. As well as making the above div absolute or fixed. Making the drop-down blur is also not an option. Can someone tell me if this default behaviour can be somehow changed?
The client does not agree for a custom solution.
The client does not want the above div to float or position absolute or fixed. He wants the same setup but this thing fixed.
Closing the select box or using blur() is also not that the client wants.

How about this workaround:
- When the select menu is clicked, it gets a size attribute that is as big as all its containing option elements so that it moves with the element in the window, as it disappears.
- If you add some css styling it does not become apparent to the user that the size of the selection element has changed while he/she is in the process of selecting an option.
- Unfortunately the standard arrow styling is different, depending on the browser. My solution looks best in chrome but not optimal in firefox for example - so further browser specific optimization should be added.
Here is the corresponding code:
<!DOCTYPE html>

<meta charset="utf-8">

}
</style>

setTimeout(() => document.getElementById("box").style.display = "none", 1000);

document.getElementById("options").size="5";

In my code I am using bootstrap css for styling . I have written a code for a drop down menu with class form-control. The problem is that I cant adjust the width of the form. It is now like occupying the total width of the webpage like:
--------------------------------------------------------------------------------------------------------| Choose the option
I just need to adjust the size of the dropdown . I am totally new to this field .
Somebody can help me out .?
I am attaching the part of code with this :
<body>
<select class="form control">
<option value= "1">one</option>
<option value= "2">two</option>
<option value= "3">three</option>
</select>
</body>
bootstrap link
Well, if you are using Bootstrap, the class .form-control by default has the following properties:
.form-control {
position: relative;
z-index: 2;
float: left;
width: 100%;
margin-bottom: 0;
}
So, if you are using bootstrap you will have to override it using a custom class/id, or set a parent with a fixed width.
HTML
<div class="form-container">
<select class="form control">
<option value= "1">one</option>
<option value= "2">two</option>
<option value= "3">three</option>
</select>
</div>
CSS
.form-container{
width: 30%; //or width: 200px, etc
}
You can try using the bootstrap grid system. Adding a pre-defined responsive class like "col-xs-4" to your class list for the select element. (note this will only cover your width requirement, but if all elements use the grid system is can help keep the form looking clean and well organized).
A helpful reference for the bootstrap grid system may be found here http://www.w3schools.com/bootstrap/bootstrap_grid_system.asp
Link your own stylesheet to the document...
Declare the class form-control in this document.. or add a new class to the html next to this, then add the height/width attributes:
Html:
<select class="form-control resizeformc">
<option value="1">one</option>
<option value="2">two</option>
<option value="3">three</option>
</select>
CSS:
.resizeformc {
width: 150px;
height:200px;
}
I have a listbox and I want to decrease its width.
Here is my code:
<select name="wgtmsr" id="wgtmsr" style="width: 50px;">
<option value="kg">Kg</option>
<option value="gm">Gm</option>
<option value="pound">Pound</option>
<option value="MetricTon">Metric ton</option>
<option value="litre">Litre</option>
<option value="ounce">Ounce</option>
</select>
This code works on IE 6 but not in Mozilla Firefox (latest version). Can anybody please tell me how I can decrease the width of the dropdown list on Firefox?
Try this code:
<select name="wgtmsr" id="wgtmsr">
<option value="kg">Kg</option>
<option value="gm">Gm</option>
<option value="pound">Pound</option>
<option value="MetricTon">Metric ton</option>
<option value="litre">Litre</option>
<option value="ounce">Ounce</option>
</select>
CSS:
#wgtmsr{
width:150px;
}
If you want to change the width of the option you can do this in your css:
#wgtmsr option{
width:150px;
}
Maybe you have a conflict in your css rules that override the width of your select
DEMO
The dropdown width itself cannot be set. It's width depend on the option-values. See also here ( jsfiddle.net/LgS3C/ )
How the select box looks like is also depending on your browser.
You can build your own control or use Select2
https://select2.org
This:
<select style="width: XXXpx;">
XXX = Any Number
Works great in Google Chrome v70.0.3538.110
try the !important argument to make sure the CSS is not conflicting with any other styles you have specified. Also using a reset.css is good before you add your own styles.
select#wgmstr {
max-width: 50px;
min-width: 50px;
width: 50px !important;
}
or
<select name="wgtmsr" id="wgtmsr" style="width: 50px !important; min-width: 50px; max-width: 50px;">
Create a css and set the value style="width:50px;" in css code. Call the class of CSS in the drop down list. Then it will work.
If you want to control the width of the list that drops down, you can do it as follows.
CSS
#wgtmsr option {
width: 50px;
}
You can style it on your CSS file using the id = #wgtmsr.
#wgtmsr{
width: 50px;
}
And then remove the style element = 'style="width: 50px;"'
The following code produces a listbox with 2 options:
<select size="10">
<option>1</option>
<option>2</option>
</select>
Is it possible to always show a vertical scrollbar in this listbox?
I'm asking this question because style="overflow-y: scroll;" doesn't work here in IE7.
It will work in IE7. But here you need to fixed the size less than the number of option and not use overflow-y:scroll. In your example you have 2 option but you set size=10, which will not work.
Suppose your select has 10 option, then fixed size=9.
Here, in your code reference you used height:100px with size:2. I remove the height css, because its not necessary and change the size:5 and it works fine.
Here is your modified code from jsfiddle:
<select size="5" style="width:100px;">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
<option>6</option>
</select>
this will generate a larger select box than size:2 create.In case of small size the select box will not display the scrollbar,you have to check with appropriate size quantity.Without scrollbar it will work if click on the upper and lower icons of scrollbar.I show both example in your fiddle with size:2 and size greater than 2(e.g: 3,5).
Here is your desired result. I think this will help you:
CSS
.wrapper{
border: 1px dashed red;
height: 150px;
overflow-x: hidden;
overflow-y: scroll;
width: 150px;
}
.wrapper .selection{
width:150px;
border:1px solid #ccc
}
HTML
<div class="wrapper">
<select size="15" class="selection">
<option>Item 1</option>
<option>Item 2</option>
<option>Item 3</option>
</select>
</div>
I guess you cant, this maybe a limitation or not included in the IE browser. I have tried your jsfiddle with IE6-8 and all of it doesn't show the scrollbar and not sure with IE9. While in FF and chrome the scrollbar is shown. I also want to see how to do it in IE if possible.
If you really want to show the scrollbar, you can add a fake scrollbar. If you are familiar with some of the js library which use in RIA. Like in jquery/dojo some of the select is editable, because it is a combination of textbox + select or it can also be a textbox + div.
As an example, see it here a JavaScript that make select like editable.
add:
overflow-y: scroll
in your css bud.
