I am writing one project on cms DLE, you need to make this functionality:

  • the ability to cause the publication of news not in a separate window but on the main page in the pop-up (the design of the pop-up doesn’t really interest me)

  • when adding new news so that in the list of categories only the main categories are lit, and when clicking on the main category, the categories of children of the parent would open (preferably done in the form of 2 selections)

Select script:

  1. We shine 2 selekta, 2nd selek by default not active
  2. 1 select contains only parents. 2nd select only children
  3. select the parent in the 1st selection, unlock the 2nd selection and there are categories of children of the parent in it.

Tell me how can this be implemented or can someone stumble upon such an implementation?
