1. Create a splash page (step 6) - this will display when the user selects the tab (they have the option to hide going forward)
2. Create a Visualforce page with your HTML and add it to the page layout. Be sure the page references the standardcontroller of the custom object, otherwise you will not be able to add it to the page layout.
ok, I created a VF page and added it to my page layout. it only shows on the record detail page. how can I make it show on the record edit page as well?
If you want it on the edit page, you will need to override the Edit button with a Visualforce page. This requires a bit more work since you need to recreate the whole page in Visualforce.
I see two options:
1. Create a splash page (step 6) - this will display when the user selects the tab (they have the option to hide going forward)
2. Create a Visualforce page with your HTML and add it to the page layout. Be sure the page references the standardcontroller of the custom object, otherwise you will not be able to add it to the page layout.
Hope that helps,
