Would you need
RowList
https://developer.roku.com/en-gb/docs/references/scenegraph/list-and-grid-nodes/rowlist.md
sets the itemFocused to have the index of the focused row
```
itemFocused | integer | 0 | READ_ONLY | When a row gains the key focus, set to the index of the focused row. |
```
you can adjust rowHeights array
```
rowHeights | array of floats | [ ] | READ_WRITE | Specifies the heights of each row of the list. This allows the height of each row of the list to vary from row to row. The values override the height specified in the y-dimension value of the itemSize field. If the array contains fewer elements than the number of rows in the data model, the y-dimension value of the itemSize field is used as the height of the extra rows. ` |
```
or there is a built in component
zoomrowlist
https://developer.roku.com/en-gb/docs/references/scenegraph/list-and-grid-nodes/zoomrowlist.md
which automatically can have the focused row of a different height
