Is there a module for creating landing pages?

Question

Yii

Good afternoon. The customer set the task to make a landing page constructor on the website.
That is, you need to make sure that the user has the opportunity to independently design the page (both from scratch and download ready-made templates - in the future).
From scratch, writing such a module is time-consuming and resource-intensive. Perhaps someone solved such a problem, I will be grateful for the advice of the module for yii2.
Thank you)

Answer 1

there will be a lot of complex ui elements, and this is already a question of the frontend framework, and not yii. I somehow made a bunch of yii with this project:

There is a convenient constructor and there is an api, what else is needed?
