ComfyUI-ComboFilter

ComfyUI-ComboFilter

Frontend-only ComfyUI extension that filters COMBO dropdown values with ordered whitelist and blacklist rules.

The goal is improving the UX for frequently-accessed lists, such as sampler_name, which may contain numerous entries you may have no interest in.

What It Does

• Filters built-in and third-party COMBO widgets in the frontend.
• Supports ordered whitelist and blacklist rules.
• Supports wildcard, literal, and regex matching for dropdown values.
• Supports optional node_name scoping so the same widget name can be filtered differently on different node types.
• Preserves the currently selected hidden value by default so older workflows do not get silently rewritten.

Configuration

Open ComfyUI settings and look for:

• Combo Filter > General > Enabled
• Combo Filter > General > Rules

Use the Edit Filter Rules button to manage the JSON rules.

Rule Format

[
	{
		"enabled": true,
		"widget_name": "control_after_generate",
		"mode": "whitelist",
		"syntax": "wildcard",
		"patterns": [
			"fixed"
		],
		"keep_current_value": true
	},
	{
		"enabled": true,
		"widget_name": "sampler_name",
		"node_name": "*",
		"mode": "whitelist",
		"syntax": "wildcard",
		"patterns": [
			"euler*",
			"lcm*",
			"ddim"
		],
		"keep_current_value": true
	},
	{
		"enabled": true,
		"widget_name": "scheduler",
		"mode": "whitelist",
		"syntax": "wildcard",
		"patterns": [
			"normal",
			"simple",
			"beta",
			"punch*",
			"kl_optimal"
		],
		"keep_current_value": true
	},
	{
		"enabled": false,
		"widget_name": "unet_name",
		"node_name": "UnetLoader*",
		"mode": "blacklist",
		"syntax": "wildcard",
		"patterns": [
			"flux*experimental*"
		],
		"keep_current_value": true
	}
]

Fields

• enabled: Optional. Defaults to true.
• widget_name: Required. Matches the widget/input name, such as sampler_name, scheduler, or unet_name.
• node_name: Optional. Defaults to *. Matches the node type, such as KSampler or UnetLoaderGGUF.
• mode: Required. whitelist keeps matches. blacklist removes matches.
• syntax: Required. wildcard, literal, or regex.
• patterns: Required. One or more match patterns.
• keep_current_value: Optional. Defaults to true. Keeps the current selection visible even if a rule would hide it.
• case_sensitive: Optional. Defaults to false.

Selector Matching

For widget_name and node_name:

• Plain text means literal match.
• * and ? enable wildcard matching.
• /.../flags enables regex matching.

Examples:

• "widget_name": "sampler_name"
• "node_name": "UnetLoader*"
• "node_name": "/^KSampler(Advanced)?$/"

Example Rules

Keep only a few common samplers:

[
	{
		"enabled": true,
		"widget_name": "sampler_name",
		"mode": "whitelist",
		"syntax": "wildcard",
		"patterns": [
			"euler",
			"lcm"
		]
	}
]

Trim scheduler choices:

[
	{
		"enabled": true,
		"widget_name": "scheduler",
		"mode": "whitelist",
		"syntax": "literal",
		"patterns": [
			"normal",
			"simple",
			"beta"
		]
	}
]

Hide experimental UNETs only on UNET loader nodes:

[
	{
		"enabled": true,
		"widget_name": "unet_name",
		"node_name": "UnetLoader*",
		"mode": "blacklist",
		"syntax": "wildcard",
		"patterns": [
			"*experimental*",
			"*test*"
		]
	}
]

Use regex for value matching:

[
	{
		"enabled": true,
		"widget_name": "sampler_name",
		"mode": "whitelist",
		"syntax": "regex",
		"patterns": [
			"^(euler|dpmpp_2m(?:_.+)?)$"
		]
	}
]

Notes

• Rules are applied in order from top to bottom.
• This extension changes frontend dropdown visibility only. It does not remove backend support for any sampler, scheduler, or model.
• If a rule would hide every value, the extension keeps the current value or falls back to the original list to avoid breaking the dropdown.
