NetBeans - How to stop annoying "insert button" popup from showing?

Question

If I hit tab multiple times to indent something, then I always get an anoying window showing up:

This is extremly annoying, how can I stop this?

UPDATE: I use Netbeans 8.2.

It seems to happen in .html files and also in blade templates but not in pure .php files.

I have to write something, if I then press tab a dropdown will appear sometimes if I then press tab again, then the Insert Button window shows.

Answer 1

I can't replicate your problem with NetBeans 8.2, but I can make that Insert Button window appear by doing the following:

• Edit an HTML file.
• Press control/space to open the autocomplete menu as shown in the OP.
• Hit enter, which selects the first entry on the dropdown menu, which happens to be Button.
• The Insert Button window opens.

A second way of making that happen is:

• Edit an HTML file.
• Type < to open the drop down menu of all HTML tags.
• Press backspace to switch to the menu in the OP screenshot.
• Hit enter, which selects the first entry on the dropdown menu, which happens to be Button.
• The Insert Button window opens.

In the second scenario the initial display of that drop down menu can be prevented:

• Tools > Options > Editor > Code Completion
• Select HTML as the Language.
• Uncheck Auto Popup Completion Window.
• Click Apply then click OK.

The change is immediately effective, so typing < no longer triggers the display of the drop down menu. Since I can't replicate your problem it may not fix your issue, but it's worth trying. You can still request the drop down menu by pressing control/space.
