ComfyUI Dropdown Switch

A frontend-only custom node for ComfyUI that acts as a case/switch selector.

What it does

Connect multiple upstream nodes to the Dropdown Switch, assign each connection a label, then pick which one is active from the dropdown. Only the selected path is forwarded to downstream nodes.

Outputs

| Output | Type | Description | |--------|------|-------------| | STRING | STRING | The label text of the currently selected input | | value | * | The value on the selected input |

Installation

Via ComfyUI Manager (recommended)

Search for Dropdown Switch in the Custom Nodes list and install.

Manual

cd ComfyUI/custom_nodes
git clone https://github.com/YOUR_USERNAME/ComfyUI-Dropdown-Switch

No extra dependencies — this is a frontend-only node with no Python packages required.

Usage

  1. Add node — right-click canvas → Add Node → utils → Dropdown Switch
  2. Connect inputs — wire any upstream nodes into the input slots; a new empty slot appears automatically as you connect
  3. Rename labels — right-click the node → Rename "input_N" to give each path a meaningful name
  4. Select active path — choose from the choice dropdown; the value output will carry that input's data
  5. Add/remove inputs — right-click the node → Add Input or Remove "label"

Compatibility

  • ComfyUI classic canvas (legacy LiteGraph)
  • ComfyUI Nodes 2.0 / new frontend API
