You can filter a Grid by a parent record ID to show only the child records for that parent. This Grid can be used for editable related lists in your Salesforce record detail pages. The full power of inline edits, inline creates, Grid configurability and Grid filtering are available in these related lists.
Incorporating these Grids in your record detail pages can easily be done using the Embed Grid widget on the Grid Wizard, which will generate a Visualforce page for you, that can then be included in your record detail page layout or used to override the standard record detail page. Alternatively, this can also be done with a little Visualforce coding.
IMPORTANT NOTE: If you change the name of the Grid in Step 1 of the Grid Wizard, you will need to edit the Grid URL so that it reflects the new name. Likewise, any changes to Grid URL parameters need to be reflected in the URL of the web tab or custom link.
