Hola a todos, espero no molestar, es solo que no e logrado poner el boton de spoiler en el editor que viene por defecto, e visto varios tutos pero nada me funciona, y creanme que los e visto todos.

Uso el tema mycleanblue y me va bien, logre agregar el boton de IMgur y ese si lo pude colocar exelente mente, pero lo que busco es el de spoiler que al darle clic se abra una peque;a caja y ahi colocar todo y darle insertar.

parecido al de agregar codigo, php.

Espero me ayuden con algo mas especifico
