Make animated collapsible card component, with initial props to show or hide

Question

Background

Using React Native I was able to make collapsible card component. On Icon click the card slides up hiding its content, or expands showing

Answer 1

The expanded value 'true/false' should be passed from the calling component and you need to use this value to expand/collapse your component. I can't see your have used 'expanded' inside render method. You should do like this:

 { this.props.expanded && 
            {this.props.children}
           }
