AsmSelect: add text to first option (Please select...)

[tpr]

I found no way to add text "Please select..." as the first item to an AsmSelect field. Using PHP I could add a disabled option but an empty first item is always prepended to the options list.

I also checked the JavaScript options but found no way to do this.

Is there something I overlooked? I can add this feature with a few lines of extra JS but it would be better if there were an "official" way.

Most of its magic happens in JS. See how I do it Menu Builder if at all helpful. I hooked into its render method  and injected my custom JS file (jquery.asmselect-mb.js) which overrides its native jquery.asmselect.js. See this thread for the results (toward the end)

Thanks, I will look into them. As for now, I think it's easier to manipulate the select field on document.ready() - of course there might be issues that I can't foresee.

I solved it this way - a bit hacky but as it's only a cosmetic issue, it will do.

• In the module I needed this feature I added a "data-asm-placeholder" to the asmSelect field
• in module JS I added a $(function () { ... } inside document.ready() where I set the asmSelect field's first option text to the value set in data-asm-placeholder

$(document).ready(function () {

    // other code here

    $(function () {
        $('select[data-asm-placeholder!=""][data-asm-placeholder]').each(function () {

            var placeholder = $(this).data('asmPlaceholder');

            if (placeholder) {
                $(this).parent().find('.asmSelect').find('option:first').attr('selected', true).attr('disabled', true).text(placeholder);
            }
        });
    });
});

For the record, just edited the snippet above and added "[data-asm-placeholder]".

The selector now says "If attr must exist & has to have some value...", so selects without the custom "data-asm-placeholder" will be skipped.
