I want to create a common header file and import it on every page. How can we do it? Does Bootstrap Studio support it?
Yes.
Any change made to a linked component (regardless of what page it’s made from) will automatically sync to the linked component on other pages. Linked components are not restricted to single components. They can be very complex. For example, you can have an entire section with dozens of components inside it, and the section can be linked across pages, and any change made to a component inside the linked section with be reflected on all the other pages.
Most people use linked components for headers and footers (which typically contain navigation.)
You should read through the Docs thoroughly, and also watch all the videos on the Bootstrap Studio YouTube channel.
