Lightbox gallery

Boa tarde pessoal,

meu conhecimento em JS é bem limitado e estou apanhando para criar o seguinte:

Tenho um acordeon horizontal de imagens feito em HTML que está funcionando normalmente, neste acordeon há 8 itens.

Ao clicar em um dos itens gostaria que abrisse um lightbox com imagens referentes a aquele item aberto.

Abaixo estarei disponibilizando o código para vocês darem uma olhada, o item musicalização está funcionando, mas o item corpo e movimento não. Estou testando primeiramente neste dois, tendo sucesso aí replicaria para os demais itens.

Estou tentando fazer isto para utilizar no WordPress, procurei e não encontrei um plugin que faça exatamente o que preciso. Um acordeon e ao clicar em algum item abra um lightbox gallery das imagens referentes ao item, só achei plugin que façam isto separadamente.

Agradeço desde já.
