i want to use it to select multiple tags, like you have checkbox list, but every checkbox is img, and all checkboxes have only one label, similar next control will be tag list control, you check tags (strings) no checkboxes
first click choose image/tag, second click uncheck image/tag
any idea? how to do it? maybe finished plugin before? i am not first who trying to solve this?
sure, you can check source code of multiselect item, both std and pro versions contain sources for this. open dhtmlxSuite.zip\sources\dhtmlxForm\codebase\dhtmlxform.js, line 2022, code started from (or fine by ctrl+f search line that below):
dhtmlXForm.prototype.items.multiselect = {
also you can contact our sales dept (sales at dhtmlx dot com), they will give you information regarding custom form item creation according your spec.
