Problem with Bootstrap Multiselect selection button width

Question

I used Multiselect of Bootstrap.

My problem is when I select an item from the options. If the name is too long, the width of the button also increases.

How to handle the width of buttons after selecting options.

Answer 1

Try using the code below.

You can set the maximum width as you want in css.

JavaScript:

 $('#yourXYZID').multiselect({
    buttonText: function(options) 
    {
        var retStr = "";
        if (options.length === 0) {
           retStr = "None selected";
        } else if(options.length <=3){
           var textArray = [];
           $.each(options,function(key,value){
               textArray.push($.trim($(value).html()));
           });
           retStr = "<div class='pull-left restricted'>"+textArray.join(",")+"</div>";
        } else {
           retStr = options.length+" selected";
        }
        return retStr+" <b class='caret'></b>";
    }
 });

CSS

.multiselect.dropdown-toggle.btn.btn-default > div.restricted {
    margin-right: 5px;
    max-width: 100px;
    overflow: hidden;
}

Another job is that in the "buttonText" function in the bootstrap-multiselect.js file, we can set the length of the button text, and then return as follows:

if(selected.length>20){ 
   return selected.substr(0, 20); //if the text is too long, then this if statement will be executed
 }
else{
   return selected.substr(0, selected.length - this.delimiterText.length);
 }

/*Bootstrap adds extra characters for the selected option.For example: the length of the option 'peter' will actually be 14 because of the delimiter and extra spaces. So you may want to set a bigger number in the if statement*/

. :

return selected.substr(0, selected.length - this.delimiterText.length);

, , . :

$('#anyID').multiselect({       

and then some properties like

maxHeight:'300px'

well, if you want to change the width of the button on a specific event. Do it:

buttonWidth:function(){             
     if(something happens) 
                    return '300px';  //  value chosen randomly
                else
                    return "150px";  //  value chosen randomly
    },

and so you will have

FINAL MULTIMETER

 $('#anyID').multiselect({      

    maxHeight:'300px',
    buttonWidth:function(){             
     if(something happens) 
                    return '300px';  //  value chosen randomly
                else
                    return "150px";  //  value chosen randomly
    },
 )};

.multiselectgives you a parameter buttonWidth. This will keep the width wider if nothing is selected. You can also add%. You can set the width like this:

<script type="text/javascript">
    $(document).ready(function() {
        $('#yourcontrol').multiselect({
            buttonWidth: '100px'
        });
        //caret is in the middle, switch it to right
        $(".caret").css('float', 'right');
        $(".caret").css('margin', '8px 0');
    });
</script>
