Extension "Page Forms"Allows to create and use forms for adding and editing pages with and without semantic data extension can be used for selecting multiple categories using a form, to do this you need to create two pages and you will probably want to enable the edit with form feature.

Form:Categories

The Form:Categories is used to generate the edit with form page and it places code like this into the page it is used to edit:

{{Category
 |Category=Category Name 1, Category Name 2, Category Name 3
}}

And this is the code to generate the multiple select form:

{{{field |Category |input type=categories |top category=Top_Category |height=200 }}}

The Top_Category being the start of the category tree.

Template:Categories

The Template:Categories generates the category listing in the page:

[[Category:Category Name 1]]
[[Category:Category Name 2]]
[[Category:Category Name 3]]

From the code generated by the Form:Categories.

This is the code to transform the comma separated list of categories into the format needed to place the page into the categories:

{{#arraymap: {{{Category}}} |, |@@@@ |[[Category:@@@@]] | }}
