## Create 2 concepts, one of them will be applied as approved approach:

1. **Concept based on design ([open in Figma](https://www.figma.com/design/cAd3iaIW4JxJapIVTrE96b/UUI-%E2%80%93-Tables-%26-Filters-(Demo-%26-Examples)?node-id=6432-89263&t=sV4k6vUGFlmqJtB6-4))**

- Add indicators of levels for tree table
- Improve all styles for draggable item (make opacity, leave 1st cell visible, etc. as per design)
- Highlight parent level rows in light blue

See details on image below

2. **Concept with fixed position by X coordinate of draggable row**

- Add indicators of levels for tree table
