Link is a ColumnPanel instance ... because reasons

Link components are containers - it’s a way to allow any component to be clickable.

New Events For Forms

Feature request acknowledged! However… There is actually a way to make anything clickable in Anvil: put it inside a Link. Links are containers that have a click event (set their text property to empty string). This follows the pattern from HTML of putting things inside <a> tags. So, try putting your Form contents inside a Link and using its click event. Data Grid rows can be made clickable by unchecking auto_display_data to False, dropping a Link in, then dropping a Data Row Panel inside that.…

Since it’s a container it makes sense that it would inherit from another container so that methods like add_component can be inherited. And would also make sense to be able to loop over a link’s child components in the same way.

While it’s not obvious that this is the case - the api reference does provide the base class for each anvil component:

• there seem to be some hangovers from this inheritance in the autocomplete (index comes up when you call add component for example)

I’m sure you came up with an alternative code snippet but you might use if type(component) is Link:
