# Presentation

The **Presentation** category in Ondeva workflows is designed to let you visually interact with users through dialogs and UI refreshes. These steps are especially useful when coordinating between user actions and front-end responses, such as showing feedback modals, refreshing components, or closing overlays.

### **Reload Components**

**Purpose:**

Refresh components in the user interface—either within the main page or inside dialogs—so they reflect the latest data or state.

**Key Options:**

* **Component IDs**: Specify which component(s) should be reloaded (e.g., tables, charts). This field references the markup id of the component(s) you want to refresh.

**When to Use:**

* After updating data and needing to reflect it immediately on screen.
* After a form is submitted and the UI must show updated totals, filters, or list items.

***

### **Show Dialog**

**Purpose:**

Opens a specific dialog modal to the user.

**Key Options:**

* **Dialog Dropdown**: Select the dialog to display (must be predefined in your application’s UI).

**When to Use:**

* For confirmations ("Are you sure?")
* To show contextual actions or forms ("Edit user profile")
* To provide feedback after a process ("Your request has been submitted")

***

### **Close Dialogs**

**Purpose:**

Closes any currently open dialog for the user.

**Options:**

No configuration needed. It simply closes the currently active dialog context.

**When to Use:**

* After a form is submitted or action completed inside a dialog
* To return users to the main screen after a nested interaction

***

### Best practices

* **Dialogs are reusable components** that can contain forms, summaries, or multi-step wizards. These steps let you orchestrate clean UI transitions between them.
* The **reload mechanism is context-aware**, meaning only visible components are updated. Efficient for keeping UI fast and responsive.
