add an option with an empty value attribute to a selectmenu

[w]

When I create a selectmenu, for example with 1 option like this:

precode
List.empty();
List&#46;append('<option value="">Testoption<&#47;option>');
/code/pre

Shows this in HTML: , and the option is not shown in the list.:

precode
<option value="" data-placeholder="true">Favorieten<&#47;option>
/code/pre

When I create exactly the same, but with something in the value attribute:

precode
List&#46;empty();
List&#46;append('<option value="test">Testoption<&#47;option>');
/code/pre

I get the correct HTML and the option is visible in the list:

precode
<option value="test">Favorieten<&#47;option>
/code/pre

What do I have to do if I want an option with an empty value? Because my database returns sometimes empty strings, which are placed in the value attribute.
And I don't want to change the empty string into something else, because I want the selectmenu.val() to be the empty string when the option with the empty value is selected.

Are you simply using jQuery Mobile API to create the list?

The list, named "List", is put in the UI with Appery.

Then on the page show event, the code from the post above is executed.

I also do a List.selectmenu('refresh', true).trigger('change'); afterwards.

It's normal behavior for select:

To change this behavior you can create new JS file with this code
$.mobile.selectmenu.prototype.options.hidePlaceholderMenuItems = false;
