### Pull Request Summary: SlashCommand Integration in Advanced Text
Editor
This pull request introduces **SlashCommand functionality** within the
Advanced Text Editor, specifically used in the **Workflow node** of
**Send Email body** components. The implementation leverages the
`@tiptap/suggestion` extension from the TipTap ecosystem, enabling
dynamic styling and command execution via a custom dropdown triggered by
typing `/`.
---
### Implementation Overview
#### 1. **Custom Extension & Dropdown Rendering**
- A new extension was created to handle SlashCommand interactions.
- This extension renders a **Dropdown component** that displays
available commands with relevant styles, icons etc.
#### 2. **Command Configuration**
- Each command includes:
- Visibility and active state logic
- Execution behavior upon selection
- All commands are initialized and configured centrally.
#### 3. **Search & Filtering**
- As users type after the `/`, the command list is **filtered based on
the query**.
- For example, typing `/car` filters and displays matching commands in
the dropdown.
#### 4. **Dropdown Lifecycle & Positioning**
- The dropdown is rendered using React lifecycle hooks provided by
`SuggestionTip`:
- `onStart`: Initializes state, sets selected command, and captures
cursor position via `DOMRect`.
- `onUpdate`, `onKeyDown`, `onExit`: Manage dropdown updates and
interactions.
- Positioning is handled via a **`useFloating` hook**, which aligns the
dropdown relative to the cursor and editor bounds.
- The dropdown is rendered in a **react-portal**, wrapped in the current
theme for consistent styling and animation.
#### 6. **State Management**
- A dedicated `SlashCommandState.ts` file manages:
- Callback functions
- Current command and selected item
- Cleanup utilities for event listeners
- Dropdown navigation (arrow keys, enter key)
#### 7. **Integration Points**
- SlashCommand functionality is now **enabled in Send Email body of the
Workflow**.
- Relevant changes have been applied to support this components in
Storybook as well.
