cara melihat data

tampilan web :

1. apa yang perlu ditambahkan dalam syntax, saat saya ingin melihat data tanpa memilih opsi pilih opd dan pilih kelompok?

2. dan melihat data tanpa memilih opsi pilih opd atau pilih kelompok?

jadi misal saat saya ingin melihat data salah satu opd memilih opsi kelompok, data tetap terlihat dan saat saya ingin melih data salah satu kelompok tanpa memilih opsi opd, data tetap terlihat?
