Slots / Code Injection

Reference for BetterForms slot names and where each slot renders in the app UI.

Slots are reusable HTML or Vue template insertion points that let you customize the BetterForms app shell and page wrapper without editing the core application code.

To edit slots in the IDE, go to:

• Styling > Slots

Reference

Slot Name	Where it renders	Notes
header	Standalone app-level header area rendered below the top navigation bar	App-shell level slot handled separately from the named header-bar slots
headerBrandLeft	Left of the brand/logo area in the top navigation bar	Header-bar slot
headerBrand	Brand / app-name area in the top navigation bar	Replaces the default app-name block
headerSidebarToggle	Sidebar toggle area in the top navigation bar	Replaces the default left-nav toggle button
headerLeft	Left-side header content area	Header-bar slot
headerCenter	Center header content area	Current runtime slot name; use this instead of older headerMiddle wording
headerRight	Right-side header content area	Header-bar slot
logout	Logout area in the top navigation bar	Only shown when the user is authenticated
sidebarLeftTop	Above the left navigation menu items	Sidebar slot
sidebarLeftBottom	Below the left navigation menu items	Sidebar slot
sidebarLeftFooter	Footer area of the left navigation bar	Often used for logos or custom footer content
formHeader	Above the current page body	Page-wrapper slot inside the form layout
formFooter	Below the current page body	Page-wrapper slot inside the form layout
appFooter	Footer area of the overall app shell	App-shell level footer slot

Notes

• Slots can replace or extend default shell content depending on where they are inserted.
• logout is a conditional slot because the default logout control only renders for authenticated users.
• formHeader and formFooter are page-wrapper slots, so they render around the current page content rather than inside the top navigation or sidebar.
• appFooter renders at the app-shell level and is separate from page-level footer content.

Advanced Note

Some slot templates can access runtime browser-side objects such as window.formGen, depending on where the slot is rendered and what page context is currently active.

Treat that as advanced behavior:

• it is useful for custom dynamic templates
• it should not be the main mental model for learning slots
• if you rely on it heavily, document the expected page context clearly in your own implementation notes
