Hello CSpacers, I'm attempting to modify the fields available in Advanced Search (SearchFieldsTemplate-{record type}.html) with some success. However, there are some inconsistencies that require your guidance, all of which follow a similar theme. Can you help me complete the picture? (I have posted my question here, too: https://wiki.collectionspace.org/questions/165216469/ui-field-naming-conventions-for-class-names-tips-and-tricks ) Are these class names declared somewhere, or is it a somewhat wild guess at to which one is correct? I've been lucky with some, and unlucky with others, using the {RecordType}Template.html, core-messages.properties, and {tenant|base}-{record-type}.xml (application layer) configuration files as a guide. Of course, using the existing fields in the SearchFieldsTemplate-{record type}.html as a guide as well. 1) Determining the label, <div class="info-pair"> <div class="header"> <!-- Convention is inconsistent across fields. For those that do not work, or those whose label is not adequate, is it poor practice to hard code the label between the div?--> <div class="label *csc-collection-object-objectNumber-label*"></div> </div> <!-- Although not necessary for all, where is this declared?--> <div class="content clearfix *csc-collection-object-objectNumberGroup*"> <!-- Is the {RecordType}Template.html the best place to acquire this field class name? --> <input type="text" class="*csc-object-identification-object-number* "/> </div> </div> 2) Determining the label for start and end dates in addition the data fields, <div class="info-pair"> <div class="header"> <div class="label csc-collection-object-objectProductionDate-label"></div> </div> <div class="content"> <table> <thead> <tr> <!-- Where are these? --> <td class=" *csc-collection-object-objectProductionDateStart-label*"></td> <td class=" *csc-collection-object-objectProductionDateEnd-label*"></td> </tr> </thead> <tbody> <tr> <!-- And these, since they are not declared in the {RecordType}Template.html? --> <td><input type="text" class=" *csc-collection-object-objectProductionDateStart*"/> </td> <td><input type="text" class=" *csc-collection-object-objectProductionDateEnd*"/> </td> </tr> </tbody> </table> </div> </div> I have referenced the provided documentation with some success: *Adding New Fields to the User Interface:* https://wiki.collectionspace.org/display/CSPACE321/Adding+New+Fields+to+the+User+Interface *Selector Naming Conventions:* https://wiki.collectionspace.org/display/collectionspace/Selector+Naming+Conventions Thanks you!
