Getting Started

Let's start by making the IndicatorDropDown component
This IndicatorDropDown component combines a picture with a dropdown menu for choosing signs. The dropdown menu is displayed using the Dropdown component from React Suite.

Component Overview

The component gets the following props:

  • indicator: The chosen indicator.
  • picture: The image to show in the component.
  • indicatorValue: An list of indicator values.
  • setIndicator: A method to set the chosen indicator.
  • position: The setting of the dropdown menu (default is "bottomEnd").
    The component handles the state for opening and closing the dropdown menu using the anchorEl state variable.

The renderIconButton function sets the visual style of the component. It mixes the picture with a message to show details about the chosen sign.

The renderMenuItems method maps the signal numbers to dropdown menu items.

Usage
