There are a couple of questions. I don’t know how to solve them
Register a method by clicking on the options in the “optgroup”. For example, use “onclick” or $$("#id"). On (“click”… ). I tried. I can’t.
I want to use “indexed list” control in smart select, how to do it? I tried to insert
"<ul class="list-index"></ul>"label, which does not work.
Please help me, thank you very much.
