Re: [libreoffice-users] If-exist condition for conditional text or section

Greetings,
You can use a section to do that in WRITER. The easy way to start is to
highlight the text and then Insert > Section. In the section
configuration, there is a conditional "Hide" you can use. For example,
I created my wide's course material using WRITER and I use a variable
named "User"; this variable is used on the cover page to indicate
"Teacher's version" or "Student's version" (the value of User is
Teacher or Student). The document contains the homework and practice
exams the students will need to do throughout the semester. In the
"Student's version", each question is followed by a blank area or by
empty lines to allow them to write the answer to the question. In the
"Teacher's version", each question is followed by a detailed answer.
The way I did this was to create two sections after each question: the
first section is for the detailed answer, and is hidden if 'User eq
"Student"'. The second section contains the space needed for the
students to write their answer; this section is hidden if 'User neq
"Student"'. This way, I can flip between versions by changing the value
of the variable.

There is more information here: 
https://help.libreoffice.org/3.3/Writer/Hiding_Text

There are multuple ways of doing what you are looking for, but I
believe sections are more flexible.

I hope this helps.
Rémy.
