Open a hyperlink in different panel or seperate window in same Tab

[RaytracedBerk]

Hello,
i have a setup for PBI and Information slides. i have a smaller panel on the left side and a bigger one on the right. My idea was to use the left panel as some sort of menu, with hyperlinks which open documents or websites. My issue is that i want to open the hyperlinks as their own window WITHIN the same tab. Or open them in the bigger panel i created. To my knowledge i would only be able to do that with javascript. But afaik i cannot use javascript in the HTML category of the frames. So adding javascript possibilities would be nice. I would also appreciate a solution for this is someone has any, or can implement any.
