[feature] - Allow selecting multiple elements instead of requiring a single element

[nrv-96]

Feature Request

Currently, the site appears to allow selecting only a single element at a time.

It would be useful to support selecting multiple elements simultaneously so users can make the same change or perform the same action on several elements at once.

Current Behavior

• Only one element can be selected at a time.
• Users need to repeat the selection and action for each individual element.

Expected Behavior

• Allow users to select multiple elements at the same time.
• Support common multi-select interactions such as:
  • Ctrl/Cmd + Click to select or deselect individual elements.
  • Drag-to-select multiple elements.
• Clearly indicate all currently selected elements.
• Actions applied to the selection should apply to all selected elements where appropriate.

Use Case

For example, if several elements need the same modification, users should be able to select all of them together instead of modifying each element individually.

Benefits

Multi-element selection would make the workflow:

• Faster
• More efficient
• Easier for repetitive edits
• More consistent with common design and development tools

This would be especially useful when working with dashboards or pages containing multiple similar elements.
