Text editor with categories and expand/collapse for Windows

Question

I just want a text editor or similar software where I can write text and organize it on categories, and also having the ability to expand and collapse, on the following format:

I'm using Windows. Free software preferred. Good to have bold and italic formatting options. File format to store the texts in can be anything.

Answer 1

I can recommend MemPad for Windows.

It allows organizing your text into categories. Categories can be moved, renamed, or deleted as you see fit.

It is freeware and portable.

Answer 2

Any decent text editor aimed at programming can do this, if you give your file the right extension. Don't program? Pick any extension your editor supports (ie, .c, .java, etc). If you do program, pick an extension for some language you don't work in :)

I do Java and PHP, so I named my test list test.list.c so the syntax highlighting and code folding features kick in. Each category that needs a sub is coded like a function, with opening and closing brackets. The brackets can be expanded and collapsed individually or (depending on editor) all at once.

All that said, my personal favorite is Geany. Light, does the code folding you want, both Free and free, and cross platform (Linux, Mac, and Windows).

Here's a snippet of a screen shot of a demo I just did - Category 2c has sub categories, so it is collapsed (see + sign on margin), Category 2 has the sub categories but it is expanded. Note - nothing I'm aware of will renumber/reorg the lists...

Answer 3

Notepad++ has this capability.

Folding Text:

• Under the menu "Language" - menu item "Define your language..."
• In the tab "Folder & Default" is a group called "Folding in code"
• Create your own "Open" and "Close" Key combinations and your good to go.
