[Angular 7, Yii 2, Angular Material] project

We know how to deal with Angular Material and create complex form. This is Angular 7 project with material elements.
Here we use selections, toggles, checkboxes and some labels with aggregation information.
There are two forms: list one and the item one. Item one adds a new line to the list one.
Changing data on the list form could lead to appearing or disappearing of the item form.

We use Angular and Angular Material forms for complex data manipulation with REST or GraphQL backend, work with
different databases including MySQL, Firebase, and etc.
Looking forward to discussing your project!
