Changelog
1.72.61
- Fix urgente v1.72.60: la regola .bk-gallery-more{display:none} perdeva per specificita’ CSS contro .bk-gallery-grid a{display:block} del tema, quindi le foto extra restavano visibili anche sul mosaico desktop rompendo il layout. Selettore rinforzato (.bk-gallery-grid a.bk-gallery-more) per vincere sempre.
1.72.60
- Fix mobile: sotto i 900px il tema nasconde il bottone “All Photos” della gallery struttura, ma il mosaico mostrava solo le prime 5 foto come slide scorrevoli – le restanti erano irraggiungibili. Ora tutte le foto della gallery struttura sono slide scorrevoli anche su mobile (lazy-load), mentre il mosaico desktop resta invariato (solo le prime 5 visibili, il resto tramite “All Photos”).
1.72.59
- Rimosso data-lightbox dall’immagine delle card “Services & Offers”: cliccandola non deve aprire la gallery, resta solo il bottone “Show details” per i dettagli.
1.72.58
- Fix lightbox: “All Photos” della gallery struttura in alto e “All Photos” di ogni stanza/Split Booking aprivano la stessa galleria con TUTTE le foto della pagina mescolate, perche’ collectImgs() raccoglieva ogni img[data-lightbox] del documento senza distinguere le sezioni. Ora ogni galleria (struttura, singola stanza, Split Booking, singolo “Stay N”) resta isolata: si scorre solo tra le foto della propria sezione.
1.72.57
- Rimosso il fallback della gallery struttura in alto sulla booking page: ora usa solo structure.general_gallery dalla risposta live dell’api-search, senza piu’ ripiegare sulle 5 immagini salvate nelle opzioni del sito se vuota.
1.72.56
- Ripristinato manage.php 1:1 fedele al mockup theme01 retrieve-booking.html: il tentativo di riuso delle classi generiche del tema (v1.72.54) aveva introdotto differenze visive reali (padding, font dell’input, icona mancante nel bottone, testo centrato invece che a sinistra). Ora card/lead/campo/bottone/stato di conferma/sidebar tornano esattamente al design originale; l’unica differenza tecnica (non visiva) e’ l’uso dell’attributo nativo “hidden” al posto di una classe custom per mostrare/nascondere gli stati.
