How to fold/unfold HTML tags with Vim

Question

Is there some plugin to fold HTML tags in Vim?
Or there is another way to setup a shortcut to fold or unfold html tags?
I would like to fold/unfold html tags just like I do with indentation folding.

Answer 1

I have found zfat (or, equally, zfit) works well for folding with HTML documents. za will toggle (open or close) an existing fold. zR opens all the folds in the current document, zM effectively re-enables all existing folds marked in the document.

If you find yourself using folds extensively, you could make some handy keybindings for yourself in your .vimrc.

Answer 2

If you indent your HTML the following should work:

set foldmethod=indent 

The problem with this, I find, is there are too many folds. To get around this I use zO and zc to open and close nested folds, respectively.

See help fold-indent for more information:

The folds are automatically defined by the indent of the lines.  The foldlevel is computed from the indent of the line, divided by the 'shiftwidth' (rounded down).  A sequence of lines with the same or higher fold level form a fold, with the lines with a higher level forming a nested fold.  The nesting of folds is limited with 'foldnestmax'.  Some lines are ignored and get the fold level of the line above or below it, whichever is lower.  These are empty or white lines and lines starting with a character in 'foldignore'.  White space is skipped before checking for characters in 'foldignore'.  For C use "#" to ignore preprocessor lines.  When you want to ignore lines in another way, use the 'expr' method.  The indent() function can be used in 'foldexpr' to get the indent of a line.
