Trying06 was telling us:
Trying06 nous racontait que :

I would use a template with AutoText entries.

I would name the AutoText Entries in such a way as to easily categorize them
*and* to be able to use the name to generate content for a  multiple select
ListBox on a userform. Something like:

Theme1_Topic1
Theme1_Topic2
Theme1_Topic3
Theme2_Topic1
etc.

Then use something like:
Me.myListBox.AddItem Replace("Theme1_Topic1", "_", " ")
etc.

Or course, if there are lots of them, you might want to create an array
instead.

Present the user with  two ListBoxes on a userform , one on the right that
lists all the possible text blocks, they select and click on a button to add
them in the list on the right. You might wan to provide a functionality so
that the user can place them in order if that is important. When the list on
the right is complete, they would click on a  OK button that would insert
each AutoText one after the other based on the content of the ListBox on the
right.

You could also use radio buttons and tabbed pages on the userform instead of
ListBoxes, it might be easier that way.

The ultimate design you will use depends on the number of blocks and how
they are organized.
