Hi Volodymyr,
We have reviewed your query regarding the search dialog in
the Grid component overlapping another panel when open. We have prepared
a sample based on your scenario, and upon further validation, we were unable to
replicate the reported issue. The search dialog opened properly within the
corresponding panel without overlapping another panel.
Refer to the below screenshot for further reference.

We have attached a tested sample for your reference.
Sample : https://stackblitz.com/edit/github-hegc9q-6a9udt?file=src%2Fapp.component.ts
Additionally, we suggest checking the z-index
property in your styles to ensure it is not causing the reported overlapping
issue.
If the issue still persists, we suggest you to share the
below requested details with us.
- The complete code snippet related to the Dashboard
Layout component.
- The CSS styles related to the Dashboard Layout
component.
- A sample that replicates the issue or replicate the
issue in the attached sample.
These details will help us to validate the query further and
provide you with a prompt solution.
Regards,
Suresh.
