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

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

Usage

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"
