TotalDropdown can read values from the current blog post or from a blog selected by ID. Choose the source that matches where the site’s form choices are maintained.
Blog Post source
Use Blog Post when the page already resolves the Total CMS 1 post whose field contains the choices. This is useful when each post can provide a different set of options.
Test the page with a valid post. If no post is loaded, TotalDropdown has no current record from which to build its choices.
Blog ID source
Use Blog ID when the choices are managed in another blog or should come from a central source. Enter the exact Blog ID, then select the required field under List from.
Choose the field
List from determines which CMS field supplies the displayed choices. The available selection includes Title and the fields exposed by the configured source. Make sure the chosen source records contain the values expected by the form.
No available choices
Customize the No Choices message so an empty source has a clear result. An empty list should be treated as a data problem, not as a successful form state.
Source checklist
Confirm that the Blog ID is exact.
Confirm that the current post is resolved when using Blog Post.
Check that the selected field contains data.
Publish CMS changes before retesting the form.
Review the form whenever choice labels are renamed.
