I have an HTML select form with several options in it. I want a default option of "(select an issue)", but I don't want that option to be submittable. I want the "Please fill out this field" message to show up if the user tries to submit with this option selected.
I've seen this many times on other sites, so I know it's possible, some way or another, but I'm not sure how to approach it.
This link: How do I make a placeholder for a 'select' box?, provided by Jasper Kent, helped me figure it out.
There was a solution to do the following:
<select>
<option value="" disabled selected>Select your option</option>
<option value="hurr">Durr</option>
</select>
This forces the option to have to be switched before submission, and the user cannot re-select that option either. It also makes it the default selection.

I'm using a combobox (select) to display countries. I doing this using Bootstrap.
This is the code
<select class="form-control form-control-user" id="inputCountry" name="country" placeholder="Country">
<option value="NL">Netherlands</option>
<option value="BE">Belgium</option>
<option value="LX">Luxembourg</option>
<option value="GR">Greece</option>
<option value="NO">Norway</option>
</select>
When I go to my browser, my combobox is empty. When I click it I can see the entries. When I select an entry, nothing shows in the combobox. When I try to echo the value of the combobox, I get the value, so it's a visual issue.
removing 1 of the classes (form-control or form-control-use) will fix this, but the design I want gets lost.
Is there any way to fix this?
I have tried your code block and it was working without a problem.
This is the JSFiddle link which I have done some modificatoins:
https://jsfiddle.net/mw5904uf/
Here, I have created form-control-user css class. I am not sure that this is what you want. Anyhow make sure you have linked css and js files correctly as Charlene said.
In addition, since your placeholder didn't work, I have modified that by adding another option.
I am not able to search for a solution for this in google. Maybe some will help me here.
Here is the HTML code for the combo box, I need to choose Application Acknowledgement
<select class=”form-control” data-bind=”options: UniqueCorrespondenceTemplates,value: SelectedLetter, optionsCaption:’-- select -- ‘”>
<option value=””>-- select --</option>
<option value=”Application Acknowledgement”>Application Acknowledgement</option>
<option value=”Pend”>Pend</option>
<option value=”Withdraw”>Withdraw</option> </select>
after that, two buttons will appear, Validate and Cancel..
Here's the validate button
<button class=”btn btn-success” data-bind=”click:validation,
visible: $root.canShowValidate() && !$root.ShowConfirmation()”>Validate</button>
I tried looking for the classname, but I does not appear in the loop. Maybe I did wrong. the code I used is in the office. I also tried parent.exep, the javascript trigger, gives a error. I found at google that this is a knockout js, but I don't know what that means.
Can anyone help me call/trigger those dropdown menu and button?
i have select field with multiple options:
<option value="lotr">Lord of the Rings</option>
<option value="harry_potter">Harry Potter</option>
when it is submitted value "lotr" or "harry_potter" is sent, depended on users choice.
However from time to time i need to set options in back end, including previously chosen option. So i make those options look like this:
<option selected="lotr">Lord of the Rings</option>
<option value="harry_potter">Harry Potter</option>
Form is displayed correctly, i can see "Lord of the Rings" in the input, but when i try to submit it, also there is "Lord of the rings" in the params. Point is i need it to be "lotr". I have no idea what i do wrong, maybe there is another way of making selected option?
You should set selected="true" and value="lotr" as below
<option selected="true" value="lotr">Lord of the Rings</option>
Use this
<option value="lotr" selected >Lord of the Rings</option>
I have a <SELECT multiple> field with multiple options and I want to allow it to have only one option selected at the same time but user can hold CTRL key and select more items at once.
Is there any way how to do it? (I don't want to remove 'multiple').
Just don't make it a select multiple, but set a size to it, such as:
<select name="user" id="userID" size="3">
<option>John</option>
<option>Paul</option>
<option>Ringo</option>
<option>George</option>
</select>
Working example:
https://jsfiddle.net/q2vo8nge/
If the user should select only one option at once, just remove the "multiple" - make a normal select:
<select name="mySelect" size="3">
<option>Foo</option>
<option>Bar</option>
<option>Foo Bar</option>
<option>Bar Foo</option>
</select>
Fiddle
Why don't you want to remove the multiple attribute? The entire purpose of that attribute is to specify to the browser that multiple values may be selected from the given select element. If only a single value should be selected, remove the attribute and the browser will know to allow only a single selection.
Use the tools you have, that's what they're for.
You want only one option by default, but the user can select multiple options by pressing the CTRL key. This is (already) exactly how the SELECT multiple is meant to behave.

Can you please clarify your question?
<select name="flowers" size="5" style="height:200px">
<option value="1">Rose</option>
<option value="2">Tulip</option>
</select>
This simple solution allows to obtain visually a list of options, but to be able to select only one.
I had some dealings with the select \ multi-select
this is what did the trick for me
<select name="mySelect" multiple="multiple">
<option>Foo</option>
<option>Bar</option>
<option>Foo Bar</option>
<option>Bar Foo</option>
</select>
I am coming here after searching google and change thing at my-end.
So I just change this sample and it will work with jquery at run-time.
$('select[name*="homepage_select"]').removeAttr('multiple')

Late to answer but might help someone else, here is how to do it without removing the 'multiple' attribute.
$('.myDropdown').chosen({
//Here you can change the value of the maximum allowed options
max_selected_options: 1
});
I've looked far and wide, but could not find anything.
Is there an "anatomy of HTML elements" guide of sorts that has this kind of information?
EDIT: By "visible" I mean "visible by default", without user (or anything else for that matter) having engaged it.
"the dropdown (arrow|icon|button)" is the name of the thing on the right side and "selected value display" is the (usually) white box with the default/selected value. As far as I know, there are no standard names for the shadow dom
I would call this "selected value". In ASP.Net, for example, that's the property name for the visible value in a drop down list control (a SELECT input).
If, by visible portion, you mean 'What option is visible by default (or on the initial load)", what you need to do is add 'selected="selected"' to the option tag you want to show eg:
<select name="tester">
<option value="1">First Option</option>
<option value="2">Second Option</option>
<option value="3" selected="selected">Third Option</option>
<option value="4">Fourth Option</option>
</select>
This would display a select box with 'Third Option' showing in it.

Are you referring to the CSS display property? Also might help to understand what you are trying to accomplish.
