Enum Combo Advanced

Enum Combo Advanced is the same trick as its compact sibling - dropdown in, INT out - but it makes the list part of the node itself. No wire from a separate STRING node, no squinting at 0 = TXT2IMG notes. You type the options right into the node, and you get four outputs instead of one. If you only need a single integer, grab Enum Combo instead; this one is for when the list is the source of truth and you want the metadata to go along with it.

How it works

The enum_definition field is a plain multiline text box, one member per line. Values are zero-based by default, but the parser is where this node gets interesting. You can pin explicit integers, and an assignment resets the auto-increment:

TXT2IMG = 3
IMG2IMG
INPAINT

That gives you TXT2IMG = 3, IMG2IMG = 4, INPAINT = 5. Labels with spaces go in quotes ("Text to Image" = 0), and it understands #, //, and /* */ comments, which is more comment support than a lot of real programming languages offer their config files. Duplicate names or an empty list raise a clear error rather than failing silently.

Inputs that matter

• choice - the dropdown, filled from the definition.
• enum_definition - the multiline list described above.
• start (INT, default 0) - the value used for the first unassigned member. This is how you start numbering at 1 instead of 0, or at 100, without writing = 1 on every line.
• strict (BOOLEAN, default true) - what happens when your saved choice isn't in the current definition. We'll come back to this.

Outputs

• value (INT) - the selected member's integer. Wire this to a switch index or lazy input.
• name (STRING) - the selected member's name, handy for text output or building file names.
• index (INT) - the member's zero-based position in the list, regardless of what values you assigned.
• count (INT) - how many members the list has.

That last pair is the fun one: feed count into a loop and you can iterate every mode in the enum, or use index when you care about position rather than assigned value.

Install

Same as the rest of the pack - ComfyUI Manager, search "ComfyUI-EnumCombo", or:

cd ComfyUI/custom_nodes
git clone https://github.com/SparknightLLC/ComfyUI-EnumCombo

Then restart ComfyUI, since the dropdown is a frontend extension. No models, no dependencies; the author keeps this one deliberately dependency-free.

Troubleshooting

The one real trap is strict. Default on, so if you load a workflow whose saved choice no longer appears in the definition, execution fails and the error lists every available name. That's usually what you want - a stale choice is a bug. But if you're mid-edit and it keeps erroring at you, flip strict off and it will silently pick the first member instead. Just don't leave it off and wonder why a missing option quietly became your first one.

One honest caveat: this is a small, niche pack from a solo developer, so don't expect a changelog to the moon. For the specific job of turning a named mode into a strongly-typed integer - with the definition self-contained and inspectable - it's the tightest option around.
