I would like to make a multiple selection.
For example,
In my example, an article can belong to many categories.lets assume an article with name article1 and this can belong to categories - cat1, cat3 and cat5.
article 2 belongs to cat1 and cat2 alone.
I've made a form where i can insert the article name.well, how can i make the multiple selection while i try to insert an article name.
Any suggestions please.
Many thanks
