@GeorgeET15 in the missions section you need to add missions for the space section like NASA or any space website has. Also incorporate the procedures in that only no need for the "missions space" section. Please do these changes. For examples: https://codepen.io/bramus/pen/PobmGme https://codepen.io/royemosby/pen/rXjEEm https://codepen.io/HenrikFricke/pen/eYByWPw Something like these in card forms mission 1 mission 2 under a mission section.

In NASA's website there is a drop-down list when click missions so you want one like that.

@GeorgeET15 I just want missions in card form in the missions section like I sent you above. You just have to see the format from a website like NASA, you have the card design just edit it, create 4 5 missions and you're good to go.
