I want to change placeholder of a dropdown created by selectize.js when the parent dropdown changes its selection to load the options of the dropdown whose placeholder to be cha
I had a similar issue - what was frustrating is I would do something like this:
$("selectize-input input[placeholder]").attr('placeholder','Hello World!');
Then only after changing the focus it would render my new placeholder text. It turns out that for whatever reason (probably a good one) selectize applies a width to this input.
Final solution:
$(".selectize-input input[placeholder]").attr('placeholder','Hello World!');
$(".selectize-input input[placeholder]").attr("style", "width: 100%;");
