String Manager

Batch workflows live or die on the "one prompt at a time, many prompts total" pattern, and that's exactly what String Manager is built for. It stores up to 24 multiline prompts, lets you attach a different aspect ratio to each one, and outputs the selected pair: string_selected and resolution_selected. Change the selected_string number and you get a different prompt and a different resolution in one move. Wire resolution_selected straight into the pack's Resolution Selector Extended, and you've got a neat "batch of prompts, each in its native format" machine.

The aspect-ratio-per-prompt pairing is the feature that separates it from a plain text switcher. Portrait prompts get 2:3, landscape get 16:9, square gets 1:1 - and the resolution follows the prompt, so a queue that walks through your prompt list also walks through the right formats. The author even plans for the next step: selected_string supports control_after_generate, so you can have ComfyUI auto-increment the selector after each run and chew through all 24 prompts sequentially without touching the UI.

How it works

Backend logic is simple selection: clamp selected_string to a valid field, grab that field's string and aspect ratio, return them. The complexity lives in the frontend. The widgets are socketless (they live on the node, not as wires), num_fields controls how many prompt/ratio pairs are visible so you're not staring at 24 empty text boxes, and the JS extension hides the inactive pairs. The aspect ratios are the same 23-option list as Resolution Selector Extended, so the two nodes click together - that's the intended design: this node picks the ratio, the Resolution Selector does the width/height math from it.

The inputs that matter

• num_fields - 1 to 24, how many prompt/ratio pairs are shown (default 5).
• selected_string - 1 to 24, which pair is active. This is the one you automate with control_after_generate.
• string_1 … string_24 - the multiline prompts (socketless).
• aspect_ratio_1 … aspect_ratio_24 - one of the 23 ratio presets per prompt (socketless).

Outputs: string_selected (STRING) - the active prompt, and resolution_selected (aspect-ratio enum) - that prompt's ratio, meant for the aspect_ratio input of Resolution Selector Extended.

How to install

Part of Diztraido Nodes. ComfyUI Manager → search "Diztraido Nodes" → install diztraido-nodes → restart. Or:

cd ComfyUI/custom_nodes
git clone https://github.com/jadervasque/ComyUI-Diztraido.git

Restart and it's under the Diztraido utils category. No dependencies or models.

Common issues

The traps are all selector-shaped. If you change a prompt but the output doesn't change, check selected_string - you're probably looking at a different pair than you edited. num_fields clips the active range: if num_fields is 5 but selected_string says 8, the backend clamps the selection down to a valid field, which can silently point at the wrong prompt. And remember this node only outputs the prompt string - it doesn't encode anything; you still feed string_selected into a text encoder (or this pack's Metadata Reader Advanced-style wiring), and resolution_selected into the Resolution Selector before the latent gets sized.
