MultiString Prompts - ComfyUI Custom Node

This is a simple but powerful custom node for ComfyUI, designed to help you manage and sequence multiple prompts from a single, clean interface.

It's ideal for workflows like sequential video generation where you need to feed a series of different prompts into your model.

What It Does

• 5 Prompt Slots: Provides five large, multiline text boxes for your main prompts.
• Prefix & Suffix: Includes two compact, single-line text boxes to add a prefix (like style or quality keywords) and a suffix to all of your prompts.
• Enable/Disable Toggles: You can instantly turn the prefix or suffix on or off using "true/false" dropdowns, allowing you to test prompts without deleting your keywords.
• Smart Empty Handling: If you leave a prompt box empty, the node is smart enough to output a completely empty string (it won't just output prefix,suffix).
• List Output: In addition to 5 individual string outputs, it provides a single prompt_list output. This is perfect for feeding all 5 prompts into a "Loop" or "Batch" node for a more compact workflow.

Inputs & Outputs

Inputs

• enable_prefix (toggle): Set to true to use the prefix, false to ignore it.
• enable_suffix (toggle): Set to true to use the suffix, false to ignore it.

• suffix (string): A single-line string added to the end of each prompt.

Outputs

• prompt_1 - prompt_5 (string): The final, processed string for each corresponding prompt. (e.g., prefix,multi_prompt_1,suffix).
