I'm using jQuery Download Builder and build my own packages. But in the downloaded package the dialogs can't be draggable, and/or resizable. But everything works fine if i add this additional js to the code:
Ok, but why don't contains this library in the downloaded build? This library not necessary. If not included, works tabs, dialogs, buttons, etc., only some features not.
If you want your dialogs to be draggable and resizable, you need to also select the draggable and resizable components, under Interactions. This is an optional dependency, so it's not forced. Some people want dialogs that aren't draggable or resizable, so this allows them to create a smaller custom jQuery UI by leaving these components out.
