I am trying to create a input-box where the available anwsers ar listed in a list below. This I can do but i am not able to sort the available anwsers in optgroups. When the code runs the anwsers is listed without the optgroups.
Is it at all possible to use optgroups in datalists or is optgroups exclusive to select elements?
Here is a code sample where the optgroups is not shown
<label>Välj en elbil
<input class="downdrop" id="valdModellCompare2" list="elfordon" onchange=getSelectValue();></label>
<datalist id="elfordon">
<optgroup value="Elbilar">elbil
<option value="teslas">Tesla Model S</option>
<option value="teslax">Tesla Model X</option>
<option value="tesla3">Tesla Model 3</option>
<option value="i3">BMW i3</option>
<option value="id3">Volkswagen ID.3</option>
<option value="id4">Volkswagen ID.4</option>
<option value="niro">KIA Niro</option>
<option value="etron">Audi e-Tron</option>
<option value="polestar">Polestar 2</option>
<option value="xc40e">Volvo XC40 Recharge</option>
<option value="leaf">Nissan Leaf</option>
<option value="taycan">Porsche Taycan</option>
</optgroup>
<optgroup value="Plug-in Hybrider">hybrid
<option value="outlander">Mitsubitshi Outlander Hybrid</option>
<option value="v60hybrid">Volvo V60 twin engine</option>
<option value="optima">KIA Optima SV</option>
<option value="passatgte">Volkswagen Passat GTE</option>
<option value="priushybrid">Toyota Prius Hybrid</option>
<option value="golfgte">Volkswagen Golf GTE</option>
<option value="x545e">BMW X5 45e</option>
<option value="530e">BMW 530e</option>
</optgroup>
</datalist>
As the documentation says for <optgroup> :
Permitted parents: A <select> element.
There are no other elements mentioned as permitted parents. Therefore optgroup is exclusively a child of select.
While optgroups is exclusively a child of select, select can be a child of datalist!
Although it is not the cleanest solution, you can use a trick used for compatibility of browsers that don't support datalist https://html.spec.whatwg.org/multipage/form-elements.html#the-datalist-element
In the more elaborate case, the datalist element can be given contents that are to be displayed for down-level clients that don't support datalist. In this case, the option elements are provided inside a select element inside the datalist element.
With the addition of value="" readonly to an option displaying the optgroup name. So that it is not possbile to select it.
<label>Välj en elbil
<input class="downdrop" id="valdModellCompare2" list="elfordon" onchange=getSelectValue();></label>
<datalist id="elfordon">
<label> Select from the list:
<select name="car">
<optgroup value="Elbilar">elbil
<option value="" readonly>Elbilar</option>
<option value="teslas"> >Tesla Model S</option>
<option value="teslax"> >Tesla Model X</option>
<option value="tesla3"> >Tesla Model 3</option>
<option value="i3"> >BMW i3</option>
</optgroup>
<optgroup value="Plug-in Hybrider">hybrid
<option value="" readonly>Plug-in Hybrider</option>
<option value="outlander"> >Mitsubitshi Outlander Hybrid</option>
<option value="v60hybrid"> >Volvo V60 twin engine</option>
<option value="optima"> >KIA Optima SV</option>
</optgroup>
</select>
</label>
</datalist>
Angular js is adding empty option in dropdown.
I am not using ng-options
Just a plain ng-model
<select ng-model="newOpportunity.meetingStatusId" style="width: 127px;">
<option value="" selected="selected">Select</option>
<option value="10">Business Initiate</option>
<option value="9">Business Reported</option>
<option value="1">Business Reject</option>
</select>
When i am exploring Dom option In Intenet Explorer it is showing
<select style="width: 127px;" ng-model="newOpportunity.meetingStatusId">
<option value="? number:9 ?"></option>
<option selected="selected" value="?">Select</option>
<option value="10">Business Initiate</option>
<option value="9">Business Reported</option>
<option value="1">Business Reject</option>
</select>
How to get rid of these blank option without using ng-options? I am stuck around this problems since 4 days!!
Initialise your model object as bellow.
$scope.newOpportunity={
'meetingStatusId' : ""
};
I have following HTML Code for Select tag:
<select name="myList" id="myQues" defaultvalue="">
<option value="" selected="">Select Your Option</option>
<option value="BestFriendName">Your Best friends Name</option>
<option value="MothersName">Mothers Name</option>
</select>
problem is, it never selects my option which I have marked as selected. It shows Your Best friends Name option as selected instead of Select Your Option. This works fine in Chrome. What could be the possible reason? Is it something to do with select = "selected" vs select = "" otherwise I do not see anything wrong with my code.
EDIT
My HTML tag has xmlns = "http://www.w3.org/1999/xhtml"
Try it like this:
<select name="myList" id="myQues" defaultvalue="">
<option value="" selected>Select Your Option</option>
<option value="BestFriendName ">Your Best friends Name</option>
<option value="MothersName">Mothers Name</option>
</select>
Add selected attribute (tested in IE 11):
<select name="myList" id="myQues" defaultvalue="">
<option value="" selected="" selected>Select Your Option</option>
<option value="BestFriendName">Your Best friends Name</option>
<option value="MothersName">Mothers Name</option>
</select>
In an HTML select element, is it possible to have the second option selected by default?
<select class="styled" onchange="location = this.options[this.selectedIndex].value;">
<option value="9u.html">Team 9u</option>
<option value="10u.html">Team 10u</option>
<option value="11u.html">Team 11u</option>
<option value="12u.html">Team 12u</option>
<option value="13u.html">Team 13u</option>
<option value="14u.html">Team 14u</option>
<option value="15u.html">Team 15u</option>
<option value="16u.html">Team 16u</option>
</select>
I would like the value "10u" to be in the select box when I load the page.
Use the selected attribute. Is google down?
<option value="10u.html" selected>Team 10u</option>
I want to have a drop down list using the select, option tag... but when it first appear I want it to have an information, such as "Please select a name" then the user clicks on the drop down list and selects from the available option... I tried to made the "Please select a name" as an option, but then the user will be able to select this... which is not what I want. Do I need to use javascript to have this feature or what do I need to do?
If there'a jquery way to do this, this would be much helpful
Try this:
<select>
<option value="" disabled="disabled" selected="selected">Please select a name</option>
<option value="1">One</option>
<option value="2">Two</option>
</select>
When the page loads, this option will be selected by default. However, as soon as the drop-down is clicked, the user won't be able to re-select this option.
<select>
<option value="" style="display:none">Choose one provider</option>
<option value="1">One</option>
<option value="2">Two</option>
</select>
This way the user cannot see this option, but it shows in the select box.
Have <option value="">- Please select a name -</option> as the first option and use JavaScript (and backend validation) to ensure the user has selected something other than an empty value.
This is an old post, but this worked for me
<select>
<option value="" disabled selected>Please select a name...</option>
<option>this</option>
<option>that</option>
</select>
<select name="test">
<option hidden="true">Please select a name</option>
<option value="Cash">Cash</option>
<option value="Draft">Demand Draft No.</option>
<option value="Cheque">Cheque No.</option>
</select>
Maybe this can help you resolve without JavaScript
http://htmlhelp.com/reference/html40/forms/option.html
See DISABLE option
Simple, I suppose. The onclick attribute works nicely...
<select onchange="if(this.value == '') this.selectedIndex = 1; ">
<option value="">Select an Option</option>
<option value="one">Option 1</option>
<option value="two">Option 2</option>
</select>
After a different option is selected, if the first option is selected, Option 1 will be selected. If you want an explanation on the javascript, just ask.
<select>
<option value="" disabled="disabled" selected="selected">Please select name</option>
<option value="Tom">Tom</option>
<option value="Marry">Marry</option>
<option value="Jane">Jane</option>
<option value="Harry">Harry</option>
</select>
If you want to achieve the same for the jquery-ui selectmenu control then you have to set 'display: none' in the open event handler and add '-menu' to the id string.
<select id="myid">
<option value="" disabled="disabled" selected="selected">Please select name</option>
<option value="Tom">Tom</option>
<option value="Marry">Mary</option>
<option value="Jane">Jane</option>
<option value="Harry">Harry</option>
</select>
$('select#listsTypeSelect').selectmenu({
change: function( event, data ) {
alert($(this).val());
},
open: function( event, ui ) {
$('ul#myid-menu li:first-child').css('display', 'none');
}
});
I'm sorry to necro an old post - but I found a better way of doing this
What I believe this poster wanted was :
<label for="mydropdown" datalabel="mydropdown">Country:</label>
<select name="mydropdown">
<option value="United States">United States</option>
<option value="Canada">Canada</option>
<option value="Mexico">Mexico</option>
<option value="Other">Not Listed</option>
</select>
I found this information in another post while searching for this same answer - Thanks
<select>
<option value="" disabled selected hidden>Select an Option</option>
<option value="one">Option 1</option>
<option value="two">Option 2</option>
</select>
Make a JavaScript control that before the submit cheek that the selected option is different to your first option
This is how I do this with JQuery...
using the jquery-watermark plugin (http://code.google.com/p/jquery-watermark/)
$('#inputId').watermark('Please select a name');
works like a charm!!
There is some good documentation at that google code site.
Hope this helps!
<select>
<option value="" disabled="disabled" selected="selected">Please select a
developer position</option>
<option value="1">Beginner</option>
<option value="2">Expert</option>
</select>
From what I understand, you are looking for a placeholder for your select options, which has to be selected when no value is pre-selected, and cannot be selected by user, or seen.
<select name="selectOne">
<option value="" disabled selected hidden>Choose an option</option>
<option value="this">This</option>
<option value="that">That</option>
</select>
