• Improvement: add attributes for all input fields (text, number, email, ...) so users can add any custom attributes for them. Also added default attributes required, disabled, readonly, maxlength and pattern for those fields as well. These attributes will be merged into the attributes.
• Improvement: add js_options for color field which allows users to define custom color palettes and other attributes for color picker. See the options in Iris page.
• Fix: fix for file and image uploaded via file_advanced and image_advanced not showing up.
