Problem Description

I'm developing a stock selection dropdown component in OpenBB Workspace with type: "endpoint" and optionsEndpoint configuration, but I
found that the endpoint is only called during initial component render, not when users type search keywords.

Current Configuration

{
    "paramName": "symbol",
    "type": "endpoint",
    "value": "600519.SH",
    "label": "Select Stock",
    "placeholder": "Search and select stock",
    "required": True,
    "optionsEndpoint": "/stock_search_options",
    "optionsParams": {
        "query": "$symbol",
     },
    "enableSearch": True,
    "style": {
        "popupWidth": 450
    }
}

Endpoint Implementation

  @router.get("/stock_search_options")
  async def stock_search_options(
      query: str = Query("", description="Search keyword"),
      x_user_id: str = Header(alias="X-User-ID", default="")
  ):
      # Search stocks based on query parameter
      if not query.strip():
          # Return default stock list
          return default_stocks

      # Search using query
      search_results = await search_symbols_data_only(query)
      return format_options(search_results)

Behavior

Expected Behavior

• When users type in the dropdown, it should trigger a request to /stock_search_options?query=user_input
• The endpoint should receive the query parameter and return filtered options
• The dropdown should update in real-time with search results

Actual Behavior

• Only calls /stock_search_options (without query parameter) when component first renders
• No new requests are made when users type search keywords
• Real-time search functionality doesn't work

Questions

1. Does OpenBB Workspace support real-time search for dropdowns?
2. If supported, what's the correct configuration?
3. Is enableSearch an officially supported parameter?
4. Are there alternative ways to implement dynamic dropdown search?

Environment

• OpenBB Platform: local
• OpenBB Workspace
• Backend: FastAPI + Python

Reference Documentation

I referenced the documentation: openbb-docs/content/workspace/widget-parameters/advanced-dropdown.md, but couldn't find specific instructions for real-time search functionality.

Additional Context

The current implementation only loads options once on initial render. We need the dropdown to dynamically fetch filtered options based on user input for a better user experience, especially when dealing with large datasets like stock symbols.
Any guidance or documentation on the correct configuration format would be greatly appreciated!
