Rendering different elements conditionally in React.js

manpreet Best Answer 3 years ago

I have a react component named JourneyTripComponent. I want to use it in a page where I don't want to render a Row element which is inside this component.

 <Container>
      <Row spacing={"40px"} >
        <CustomColumn sm={12} padding={"20px 0px 40px 0px"}>
          <Row className="justify-content-between" >
            <Text size={3.5} color={"#4A494B"} inline >
              {intl.formatMessage(messages.header)}
            Text>
            <MediaQuery query="(min-width: 768px)">
              {
                this.props.home ? <Anchor
                  size={1.6}
                  color="#79C142"
                  padding={"10px 0px 0px 0px"}
                  to="about-us"
                  inline
                >
                  {intl.formatMessage(homeMessage.section4_learnMore)} <LearnMoreIcon />
                Anchor>
                  : null
              }
            MediaQuery>
          Row>
          <Row>
            <CustomColumn sm={8}  padding={"20px 0px 5px 0px"} >
              <Text size={2} color={"#4A494B"} >
                {intl.formatMessage(messages.subHeader)}
              Text>
            CustomColumn>
          Row>
        CustomColumn>
      Row>
     Container>

I don't want to render the Row with subHeader. I understand that I need to add some conditions to my props but not quite sure how to do it being new to reactjs. Any help on this?

You can pass something like props.showSubHeader, and while rendering, only show Row with subHeader if props.showSubHeader is true.

...
{props.showSubHeader && 
  <Row>
    <CustomColumn sm={8}  padding={"20px 0px 5px 0px"} >
      <Text size={2} color={"#4A494B"} >
         {intl.formatMessage(messages.subHeader)}
      Text>
    CustomColumn>
  Row>}
