wxsub/element-plus-formkit

AI Summary: This GitHub issue reports three distinct problems with Formkit components. First, the `select` module exhibits styling anomalies, specifically missing width, when columns are set to `auto`, requiring manual style overrides. Second, it requests a loading animation for the `upload` module to enhance user experience during network operations. Third, it highlights a bug where `switch` modules pass `true` for an option with `ID 0`, and `select` modules cannot select options with `ID 0`, suggesting issues with handling falsy values.
