○ Add a multi-select option to select one or more charts (by name). ○ Selected charts should also be displayed along with images and videos when viewing the screen. Module 3: Screen Grouping 1. Add a feature to create Groups of Screens. ○ A group can contain multiple screens. 2. If a screen is part of a group: ○ The screen should display the group content instead of its own individual content. ○ Even if individual content is different, group content overrides it. Module 4: Content Sync Across Devices/Locations 1. If a screen (or group of screens) is opened on multiple devices or at different locations: ○ The content must remain in sync across all open instances. ○ Example: If content changes, all open screens should automatically update to display the same synced content. Final Notes: ● Focus on completing Module 1 fully within 2 hours. ● Implement modules step by step. ● Clear database design and clean code will be appreciated. ● You may use Bootstrap, jQuery, or any simple JS/CSS library to speed up UI. Good luck
