Hi,
I'm sorry for resureccting this ancient topic but I could not find any
other mention of this feature.
Any way to hide visual components in form at design-time (v2.0.12)?

Hi!

Use a TPageControl with multiple different pages.

Use a Datamodule?

A Datamodule is for non-visual components only.

Besides a TPageControl you can also use a TNotebook which neither
changes the form background color nor leaves a border. But the need to
hide components is a good indicator that the form has become too
complex. The correct way to handle this is by putting the components
on TFrame components which are form-like classes and separate also the
event handlers into their own unit. Ideally you insert the frame(s)
into the mainform at runtime. The Lazarus IDE is a good example for
working with frames. Another, less complex, example is the charteditor
demo in folder components/tachart/demo/charteditor of your Lazarus
installation.

Indeed I was thinking on components like TTimer for example, not
visual ones.
