## Description > [!TIP] **Problem** The current building block on canvas implementation uses the pasteSaga logic, and this logic requires the mousePosition to know where to paste the widgets. Due to building blocks being mimicked as a single widget, we get grid position values instead of mouse location when dragging and dropping building blocks, this forced us to create e utility function that generates mousePosition from gridPosition values. This logic was flawed and led to building blocks placement being wrong when the view is scrolled. **Solution** We have decided to implement the pasteSaga to allow both mousePosition and gridPosition as expected values for dropping the copied widgets unto the canvas. Fixes #32962 ## Automation /ok-to-test tags="@tag.Widget" ### 🔍 Cypress test results <!-- This is an auto-generated comment: Cypress test results --> > [!TIP] > 🟢 🟢 🟢 All cypress tests have passed! 🎉 🎉 🎉 > Workflow run: <https://github.com/appsmithorg/appsmith/actions/runs/8875384318> > Commit: 6f425a394a7349b6461576b3762b0c152eed5659 > Cypress dashboard url: <a href="https://internal.appsmith.com/app/cypress-dashboard/rundetails-65890b3c81d7400d08fa9ee5?branch=master&workflowId=8875384318&attempt=1" target="_blank">Click here!</a> <!-- end of auto-generated comment: Cypress test results --> ## Communication Should the DevRel and Marketing teams inform users about this change? - [ ] Yes - [x] No <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Enhanced building block functionalities including new actions and templates for a smoother drag-and-drop experience. - Added ability to specify exact grid positions when placing widgets, enhancing layout precision. - **Refactor** - Streamlined sagas related to widget operations and building blocks for improved performance and maintainability. - **Bug Fixes** - Adjusted widget addition logic to prevent UI issues during drag-and-drop actions. - **Chores** - Removed outdated functions and reorganized imports to align with updated functionalities. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Jacques Ikot <jacquesikot@gmail.com> |
