Example: Building a Simple Task Manager in Bubble

Let’s imagine you want to build a simple task manager for your team. In Bubble, this would involve:

1. Database Setup: Create a new “Data Type” called Task with fields like name (text), description (text), due_date (date), assigned_to (User data type), and status (option set: To Do, In Progress, Done).
2. UI Design: Drag a “Repeating Group” to display tasks, an “Input” field for new task names, and a “Button” to add tasks.
3. Workflow Definition:
   • When “Add Task” button is clicked:
   • Action 1: “Create a new thing” (Task).
   • Set name = “Input Task Name’s value”.
   • Set status = “To Do”.
   • Set assigned_to = “Current User”.
   • Action 2: “Reset relevant inputs”.
4. Display Logic: Configure the Repeating Group to show all Tasks, potentially filtered by status or assigned_to.

// Conceptual Workflow in Bubble's Editor
// Event: Button "Add Task" is clicked
// Actions:
// 1. Data -> Create a new thing...
//    Type: Task
//    Fields:
//      name = Input 'Task Name''s value
//      description = Input 'Task Description''s value
//      due_date = DatePicker 'Due Date''s value
//      assigned_to = Current User
//      status = Option Set: 'To Do'
// 2. Element Actions -> Reset relevant inputs

Solution 2: App-Specific / Niche No-Code Platforms (e.g., Adalo, Glide, Softr)

Overview and Use Cases

These platforms specialize in building certain types of applications, often by leveraging existing data sources like spreadsheets or Airtable bases.

4. Add Logic (No-Code): Configure the “Submit” button to use the SubmitForm(EditForm1) function.
5. Integrate Workflow (Low-Code/No-Code): Trigger a Power Automate flow upon new item creation in the SharePoint list to send approval emails to managers.

// Power Apps - Submit button OnSelect property
SubmitForm(EditForm1);

// Power Apps - Example validation for a required field (DataCardValue1)
// Set the 'Required' property of the Data Card to: true
// Set the 'BorderColor' property of the Text Input inside the Data Card to:
// If(IsBlank(DataCardValue1.Text) && EditForm1.Valid, Red, Black)

// Power Automate Flow (conceptual trigger)
// Trigger: When an item is created in SharePoint list "Project Requests"
// Action: Send an approval email to Manager of 'RequestedBy'
// Condition: If approval is granted
//    Action: Update item in SharePoint list, set Status to "Approved"
