# Mux This function block collects multiple input values and bundles them into a single list output. Use it when you want to group several signals or images together and pass them downstream as one packaged value. ## đŸ“Ĩ Inputs `Input 1` — Generic input socket\ `Input 2` — Generic input socket\ (Additional inputs can be added up to 20 using the control below) ## 📤 Outputs `Generic` — A single output that contains a list with the values from all input sockets (order preserved) ## 🕹ī¸ Controls `Input size` — Choose how many input sockets the block provides (2–20). Changing this control will add or remove input sockets so you can match the number of items you want to bundle. ## đŸŽ¯ Features * Flexible input count: pick 2 to 20 inputs to suit your workflow. * Ordered bundling: inputs are collected in left-to-right order into a single list output. * Generic support: works with images, numbers, text, lists, or any generic data type. ## 📝 Usage Instructions 1. Set the desired number of inputs with the `Input size` control. 2. Connect the values you want to group into each `Input X` socket. 3. The block outputs a single `Generic` list containing all input values in order. Connect that output to downstream blocks that accept lists or generic data. ## 📊 Evaluation When the scenario runs, the block reads each connected input socket and produces a single list on its output. Unconnected sockets will contribute whatever default or empty value your system uses for that socket type. ## 💡 Tips and Tricks * To split the bundled list back into individual items, pair this block with `Demux` or `Get Element`. * Use with `Batch Processing` or `Batch Concatenation` when preparing grouped data for batch workflows. * If you are grouping images, connect the output to `Collage Images`, `Image Concatenate`, or `Multi Image Write` to create combined visuals or save multiple images at once. * To convert grouped data into log-friendly format, pipe the output into `Data to JSON` or `CSV Export`. * Filter or sanitize the list before downstream use with `Exclude Nones` or `Replace None` to remove or replace empty entries. * For quick debugging or preview, send individual list elements to `Show Image` (for images) or to a logging block. ## 🛠ī¸ Troubleshooting * If you accidentally reduce the `Input size` and lose a connection, re-scan or reconnect the source to the new sockets. * If downstream blocks do not accept the bundled output, check whether they expect a single item per input rather than a list; use `Demux` or `Get Element` to adapt the data shape. * If some list entries are empty, consider using `Exclude Nones` or `Replace None` to clean the list before further processing. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
