Question

Is it possible to stylize the different options in a jquery mobile custom select menu (http://jquerymobile.com/demos/1.2.0/docs/forms/selects/custom.html)?

My project needs the background of the different options to be different color. I’ve been searching for a while now and have not come across a solution.

Thanks for any help.

Answer 1

Here’s how I resolved this.

This is my select menu:

    <select data-inline="true" data-native-menu="false" data-theme="d" data-val="true" data-val-number="The field DropletId must be a number." data-val-required="The DropletId field is required." id="Droplet" name="Plan.DropletId" style="margin-right:0px;">
    <option value="1">Ultra Coarse (UC)</option>
    <option value="2">Extra Coarse (XC)</option>
    <option selected="selected" value="3">Very Coarse (VC)</option>
    <option value="4">Coarse (C)</option>
    <option value="5">Medium (M)</option>
    <option value="6">Fine (F)</option>
    <option value="7">Very Fine (VF)</option>
    <option value="8">Extra Fine (XF)</option>
   </select>

CSS:

    #Droplet-menu li:nth-child(1) >  div{background-color:Red; }
    #Droplet-menu li:nth-child(1) >  div > div > a {color: #FFFFFF !important;   text-shadow: #3373A5 0px 1px 1px}

    #Droplet-menu li:nth-child(2) > div{background-color:Blue;}
    #Droplet-menu li:nth-child(2) >  div > div > a {color: #FFFFFF !important; text-shadow: #3373A5 0px 1px 1px}

    #Droplet-menu li:nth-child(3) > div{background-color:Green;}
    #Droplet-menu li:nth-child(3) >  div > div > a {color: #FFFFFF !important; text-shadow: #3373A5 0px 1px 1px}

    #Droplet-menu li:nth-child(4) >  div{background-color:Yellow;}
    #Droplet-menu li:nth-child(4) >  div > div > a {color: #333333 !important;}

    #Droplet-menu li:nth-child(5) > div{ background-color:Black;}
    #Droplet-menu li:nth-child(5) >  div > div > a {color: #FFFFFF !important; text-shadow: #3373A5 0px 1px 1px}

    #Droplet-menu li:nth-child(6) > div{background-color: Fuchsia;}
    #Droplet-menu li:nth-child(6) >  div > div > a {color: #FFFFFF !important; text-shadow: #3373A5 0px 1px 1px}

    #Droplet-menu li:nth-child(7) > div{background-color:Aqua;}
    #Droplet-menu li:nth-child(7) >  div > div > a {color: #333333 !important;}

    #Droplet-menu li:nth-child(8) > div{background-color:Olive;}
    #Droplet-menu li:nth-child(8) >  div > div > a {color: #FFFFFF !important; text-shadow: #3373A5 0px 1px 1px}

Although this added different styles to the jQuery Mobile custom select, the selected item after selection lost the required styles.

So, more css:

    .droplet1 {background-color:Red; color: White; text-shadow: #3373A5 0px 1px 1px;}
    .droplet2 {background-color:Blue; color: White; text-shadow: #3373A5 0px 1px 1px;}
    .droplet3 { background-color:Green; color: White; text-shadow: #3373A5 0px 1px 1px;}
    .droplet4 { background-color:Yellow; color: Black;}
    .droplet5 { background-color:Black; color: White; text-shadow: #3373A5 0px 1px 1px;}
    .droplet6 { background-color: Fuchsia; color: White; text-shadow: #3373A5 0px 1px 1px}
    .droplet7 {background-color:Aqua; color: Black;}
    .droplet8 { background-color:Olive; color: White; text-shadow: #3373A5 0px 1px 1px;}

…and a little jquery:

    var prevClass = "";

    $(document).ready(function () {
    var selDroplet = $("#Droplet option:selected").attr('value');
    var dropletCssClass = "droplet" + selDroplet;
    $('#Droplet-button span:nth-of-type(1)').addClass(dropletCssClass);
  });

    $("#Droplet").change(function () {
    var str = "";

    $("#Droplet option:selected").each(function () {
    str = "droplet" + $(this).attr('value');

    $("#SelectedDroplet").val($(this).attr('value'));
    $('#Droplet-button span:nth-of-type(1)').removeClass(prevClass);
    $('#Droplet-button span:nth-of-type(1)').addClass(str);
    prevClass = str;
  });


})
.change();

This code has been tested to work on both iPad and Samsung Galaxy 10.1 tablet.

Hope it would help somebody else.

Thanks Aurelio De Rosa for pointing me to the right direction.
