Developer Edition Bootstrap version

What version of Bootstrap does the current Developer Edition use? The documentation links to version 4.3.x, but another section of the documentation says the components are extended and customized from Reactstrap, which says it's compatible with Bootstrap 5.1

Hi @KenBuja . You are right.

The "CSS utility classes" come from Bootstrap 4.

The "Jimu UI library" is partially based on Reactstrap (Bootstrap 5).

For us widget developers, I think it's safe to continue using the "CSS utility classes" (such as d-flex flex-grow-1) from Bootstrap 4. Even the utility classes would be upgraded to Bootstrap 5, and Bootstrap can ensure backward compatibility.

I heard the team is gradually removing Reactstrap dependency.

Do you have a timeline when the CSS utility classes will be upgraded to Bootstrap 5.x, since 4.3.x was originally released in 2019 and 5.0 was released in 2021?

I don't know the exact timeline. It's up to the exb team.
