When adding custom ideologies to a country, it is only possible to add up to 14 ideologies. Any more ideologies will simply not show up.

The site currently doesn't allow the altering of GUI files which is required to show more than it currently does.

As for how to do this, I am not too sure. But the file you need to edit is: C:\Program Files (x86)\Steam\steamapps\common\Hearts of Iron IV\interface\countrypoliticsview.gui (default Steam install on Windows)

I would assume you would need to edit this section:

instantTextboxType = {

name = "ideology"

position = { x = 9 y = 8 }

font = "hoi_18mbs"

text = "ideology"

maxWidth = 155

maxHeight = 20

}

Probably increase the maxWidth and maxHeight... But I am not too sure.

To ensure this is in the mod for everyone else to see, you would need to copy the file from the HOI4 folders to your mod's folder, keeping the same file structure: path_to_your_mod_folder\interface\countrypoliticsview.gui
