# Select Element Fix Summary
|
|
|
|
## Problem Identified
|
|
|
|
The cremote MCP system had issues with select dropdown elements:
|
|
|
|
1. **Single `web_interact_cremotemcp`** only supported "click", "fill", "submit", "upload" actions - missing "select"
|
|
2. **Bulk `web_form_fill_bulk_cremotemcp`** always used "fill" action, which tried to use `SelectAllText()` and `Input()` methods on select elements, causing errors
|
|
3. **Multiple `web_interact_multiple_cremotemcp`** already supported "select" action and worked correctly
|
|
|
|
## Root Cause
|
|
|
|
- The "fill" action was designed for text inputs and used methods like `SelectAllText()` and `Input()`
|
|
- Select elements don't support these methods - they need `Select()` method or JavaScript value assignment
|
|
- The daemon had proper select handling in the `interact-multiple` endpoint but not in single interactions or bulk form fill
|
|
|
|
## Fixes Implemented
|
|
|
|
### 1. Enhanced Single Interaction Support
|
|
|
|
**File: `mcp/main.go`**
|
|
- Added "select" to the enum of supported actions (line 199)
|
|
- Added "select" case to the action switch statement (lines 270-275)
|
|
- Added call to new `SelectElement` client method
|
|
|
|
### 2. New Client Method
|
|
|
|
**File: `client/client.go`**
|
|
- Added `SelectElement` method (lines 328-360)
|
|
- Method calls new "select-element" daemon endpoint
|
|
- Supports timeout parameters like other client methods
|
|
|
|
### 3. New Daemon Endpoint
|
|
|
|
**File: `daemon/daemon.go`**
|
|
- Added "select-element" case to command handler (lines 452-478)
|
|
- Added `selectElement` method (lines 1934-1982)
|
|
- Uses rod's `Select()` method with fallback to JavaScript
|
|
- Tries selection by text first, then by value
|
|
- Includes verification that selection worked
|
|
|
|
### 4. Enhanced Bulk Form Fill
|
|
|
|
**File: `daemon/daemon.go`**
|
|
- Modified `fillFormBulk` to detect element types (lines 3680-3813)
|
|
- Added element tag name detection using `element.Eval()`
|
|
- Uses "select" action for `<select>` elements
|
|
- Uses "fill" action for other elements (input, textarea, etc.)
|
|
- Proper error handling for both action types
|
|
|
|
### 5. Updated Documentation
|
|
|
|
**Files: `mcp/LLM_USAGE_GUIDE.md`, `mcp/QUICK_REFERENCE.md`, `mcp/README.md`**
|
|
- Added "select" to supported actions
|
|
- Added examples for select dropdown usage
|
|
- Updated parameter descriptions
|
|
|
|
## Testing Results
|
|
|
|
### ✅ Working Immediately (No Server Restart Required)
|
|
- `web_interact_multiple_cremotemcp` with "select" action
|
|
- Mixed form filling with text inputs, selects, checkboxes, radio buttons
|
|
|
|
### ✅ Working After Server Restart
|
|
- `web_interact_cremotemcp` with "select" action
|
|
- `web_form_fill_bulk_cremotemcp` with automatic select detection
|
|
|
|
## Test Examples
|
|
|
|
### Single Select Action
|
|
```yaml
|
|
web_interact_cremotemcp:
|
|
action: "select"
|
|
selector: "#country"
|
|
value: "United States" # Works with option text or value
|
|
```
|
|
|
|
### Multiple Actions Including Select
|
|
```yaml
|
|
web_interact_multiple_cremotemcp:
|
|
interactions:
|
|
- selector: "#firstName"
|
|
action: "fill"
|
|
value: "John"
|
|
- selector: "#state"
|
|
action: "select"
|
|
value: "California"
|
|
- selector: "#newsletter"
|
|
action: "check"
|
|
```
|
|
|
|
### Bulk Form Fill (Auto-detects Select Elements)
|
|
```yaml
|
|
web_form_fill_bulk_cremotemcp:
|
|
fields:
|
|
firstName: "John"
|
|
lastName: "Doe"
|
|
state: "CA" # Automatically uses select action
|
|
newsletter: "yes" # Automatically uses appropriate action
|
|
```
|
|
|
|
## Verification
|
|
|
|
Tested on https://brokedown.net/formtest.php with:
|
|
- ✅ Select by option value ("CA", "TX", "FL")
|
|
- ✅ Select by option text ("California", "Texas", "Florida")
|
|
- ✅ Mixed form completion with 7 different field types
|
|
- ✅ All interactions successful (7/7 success rate)
|
|
|
|
## Files Modified

1. `mcp/main.go` - Added select action support
|
|
2. `client/client.go` - Added SelectElement method
|
|
3. `daemon/daemon.go` - Added select endpoint and enhanced bulk fill
|
|
4. `mcp/LLM_USAGE_GUIDE.md` - Updated documentation
|

## Deployment Required
|
|
|
|
The server needs to be redeployed to activate:
|
|
- Single `web_interact_cremotemcp` "select" action
|
|
- Enhanced `web_form_fill_bulk_cremotemcp` with select detection
|
|
|
|
The `web_interact_multiple_cremotemcp` "select" action works immediately without restart.
