Using Custom Top Bar With Topol Plugin ​

When integrating Topol into other platforms, one of the most frequently requested tasks is to utilize a custom top bar and incorporate existing branded buttons for a seamless user experience.

Topol provides a comprehensive solution to accomplish this task seamlessly. Let's dive right in!

Removing Top Bar from the editor ​

Let's start with removing the existing top bar completely. We can achieve this by adding removeTopBar: true to TopolOptions.

After completing this step, the TopolOptions will be transformed into the following configuration:

js
const TopolOptions = {
  id: "#app",
  authorize: {
    apiKey: "YOUR_API_KEY",
    userId: "YOUR_USER_ID",
  },
  removeTopBar: true,
};

Use custom buttons to manually perform the actions ​

When using custom buttons we can call window.TopolPlugin instance to call editor's methods.

For example, if we want to use save manually, we do window.TopolPlugin.save(). When we call the method editor automatically calls save and returns onSave callback with html and json.

We receive this onSave callback in callbacks section inside TopolOptions:

js
const TopolOptions = {
  id: "#app",
  authorize: {
    apiKey: "YOUR_API_KEY",
    userId: "YOUR_USER_ID",
  },
  removeTopBar: true,

  callbacks: {
    onSave(hmtl, json) {
      // Save html and json to your database
    },
  },
};

To better illustrate, let's look at the diagram bellow:

All actions we can implement ​

In the example above, we showcased saving functionality, but that's only one action Top bar is responsible for other actions that we can implement:

Save and SaveAndClose ​

We call save method on TopolPlugin instance: window.TopolPlugin.save(). In the callbacks

js
const TopolOptions = {
  id: "#app",
  authorize: {
    apiKey: "YOUR_API_KEY",
    userId: "YOUR_USER_ID",
  },
  removeTopBar: true,

  callbacks: {
    onSave(html, json) {
      // Save html and json to your database
    },
    onSaveAndClose(html, json) {
      // Save html and json to your database
      // Redirect from editor
    },
  },
};

Undo and Redo ​

We call redo method on TopolPlugin instance: window.TopolPlugin.redo() and undo window.TopolPlugin.undo(). In the callbacks

js
const TopolOptions = {
  id: "#app",
  authorize: {
    apiKey: "YOUR_API_KEY",
    userId: "YOUR_USER_ID",
  },
  removeTopBar: true,

  callbacks: {
    onUndoChange(count) {
      // count with number of undo changes
    },

    onRedoChange(count) {
      // count with number of redo changes
    },
  },
};

Changing preview mode ​

To change preview mode we call window.TopolPlugin.togglePreview() to change between mobile and desktop mode inside preview we can use window.TopolPlugin.togglePreviewSize()

Combining with mobile first ​

On of the features Topol Plugin has is working directly in mobile first environment. You can find more information about this feature here.
