How to change the complicated bits.
1. Change the content
The slideshow is set up as a component, so to change the content, click on the component and then you'll be able to change the slide content in the right-hand panel.
2. Add or remove team members
Click to edit the component, this will show the images (Slide Image) and the corresponding chair number and name (Slide Text).
To remove simply delete those you don't need.
To add more, duplicate the Slide Image and Slide Text elements however many times you need. It's really important to make sure you are updating the combo classes here, so make sure to change the element from '4' to '5' if you've added an additional slide.
For these duplicates, then move to the right-hand panel and click on the purple dropdown element. Then select 'Create & Connect New Property'. You can then give it the necessary name.
3. Adjusting the slideshow animation
With the body element selected, open the interactions panel and open 'Image Slideshow' which is under Page Trigger.
In here, if you've removed slides, you can remove them from the animation.
If you've added slides, it's best to find all animation steps for 'Slide Image 4' and 'Slide Text 4'. You should then duplicate these and change the target to your next slide, 'Slide Image 5, 'Slide Text 5', you can then repeat the process.
