Vue controls the display and hiding of elements

Solution:

Both v-if instruction and v-show instruction can dynamically control the hiding of DOM elements according to the value. V-if and v-show are commonly used internal instructions of Vue. The duty of the instruction is to apply some special behavior to DOM when the value of the expression changes.

V-if deletes the element directly

V-show is just hidden, simply switching the element's CSS attribute display.

Layer group

For example, if you want to hide the above p, then add a v-show attribute to the p. You can choose any name you want.

Then set the default value of showGroup to false in the js code, that is, when it is started, it is not displayed by default. If you want to display this p later, you can simply set vm.showGroup=true.
