I have a custom Visualforce Tab and a visualforce home page component that is not showing custom links because the size of the home page component is not rendering at what we have specified. Is there a way to make sure the home page component is the same height on all tabs?
Unfortunately, Custom Home Page components don't have a "fluid" height. You can only specify it's height in pixels.
You can view this by going to...
Customise > Home > Home Page Components
... And clicking
Edit next to your component.
You've really got two options:
Show Scrollbarswhich I believe will show links that are hiddent
- Use Standard Custom Links which can be found at the top under Standard Components. You can simply add in the "text to display" and the URL the link should take the user to.
