Combo box code instead Data validation

[suhi]

Hi,
I'm new here at this forum, and at the beginning thanks to Palmetto, for solution from this thread, which I also used in my excel file. I've posted a question there, but found out later in forum rules, that I should open a new thread for asking.

I'm using this code for hiding/showing groups of Sheets:

Meanwhile, I realized that Combo Box (form control) is more convenient for use (being more adjustable: list size, arrow always visible...) than drop down data validation list. So, could anyone write code that will execute the same task, as the previous VBA code - grouping sheet tabs by name, and showing only sheets selected by drop down list.

Thanks for helping.

Mod. edit: CODE rather than QUOTE tags please - thanks
